I don't see why not.

BURN ASM BURN

 Where do those wall-crawling MJ panels come from?

I think the idea of MJ with 'powers' defeats the whole purpose of the character. 
I've always felt she was one of those characters specifically suited to ground the Spidey mythos in some level of reality. Giving her powers would just be a silly gimmick in my mind.

I prefer normal MJ.

"MJ with superpowers! That was what Firestar in Spiderman and his Amazing Friends was "

I doubt it will be anything permanent. But it will be fun to see how Peter will react to superpowered MJ although given by MJ's speech, she will gain her powers because of something Peter did.

" Don't we already have Black Cat for that? Girl with Superpowers with romantic feeling for Spidey, we're gonna turn MJ into that as well, then you have two similar characters with spiderman in the middle, that is gonna end with a fight between the 2, and the innevitable depowerement of MJ once editorial realizes they need someone in MJ's "powerless" love interest situation. "

Sure she should! 
 
And why you're at it why not just give superpowers to Aunt May, J.J., Robbie Robertson, Liz Allen, Betty Brant, Foggy Nelson, Karen Page, Perry White, Alfred and all the other supporting cast characters! Weeeee!  It worked so well for the development of Jimmy Olsen and Lois...  
 
Or perhaps we learned nothing from THE INCREDIBLES:  
Buddy: This is because I don't have powers, isn't it? Well, not every superhero has powers, you know. You *can* be super without them."
 
-sigh- 

Sure.

MJ already has superpowers... super *good looking* :o)

Peter:  Hey Mary Jane!  I have these cool super powers that have caused me to be feared, persecuted, lied about, hunted, beaten up, almost killed, bonded by an alien symbiote, had those close to me attacked and harassed, and their deaths are partially my fault.  Friendships strained, and then there's Spider Man 3.  So you want some too? 
 
Mary Jane: Uhhh?   You can keep it to yourself, Tiger. 
 
Peter: Okay.  I was just doing what Joe Quesada wants me to do. 
 
 
 
Seriously, who wants the love of their life to experience crap like that?

Personally I want to read about characters that grow and change with time.  If I want to keep reading about a regular MJ who hasn't done much in her entire life aside from being a hot normal girl who Peter has a thing for then I can pick up the hundreds of comics I've missed from before the mid nineties.  Since I know I don't, I rather see her become relevant and in this case, it means getting powers.  Otherwise, the only thing that keeps from being any other girl who can written into Pete's life is the fact that she has decades of history with him.  But when summed up, it doesn't really amount to much.  So power her up I say.  Even if temporary, it should produce from interesting scenes that could be pretty cool if done right.

I think it'd be great. Husband and wife fighting for justice together and forever. Wouldn't that be sweet?

If Marvel were to give her superpowers, they'd somehow find a way to use it to force her and Pete apart, ala Lana Lang in Smallville.

Maybe? I mean if it furthers her character. Otherwise, it'd just be campy

Would be a nice evolution of the character.
 
The side character romantic interest types never seem to gain powers permanently.. would be refreshing.

i'm not sure about powers, maybe if she trained with SHIELD and became an agent

Oh, Dan Slott. =]

I'm liking the current status quo for Peter and Carlie... So, give her powers, just don't bring them together just yet!

personally no. I like how Mary jane is right now. A regular person who is down to earth. 
 
But looking at it from a comic book geek point of view. She should have already spidery powers the moment Mary jane knocked boots with Peter Parker. If the Parker gets transformed from a spider bite that his bite directly in his vein. Think about what should have happened to Mary jane when Peter...........ok I'm going to stop this is getting to hentaish. 
 
Overall Personally no. Technically yes.  

sigh

I dunno, doesn't feel like it would work that well with Mary Jane since her main thing with Spider-man seemed to be that she was the main representation of his normal life and everything he might be leaving behind for his life of protecting others. I think it kind of worked with Betty Ross, but I can't see it being a normal course of action for every superhero with a regular girlfriend.

I wouldnt want to see her with superpowers. I could see things taking a bad turn if that happened

 
 I want to see where this story line is going first before I make and final judgment calls.

that would be interesting.... in fact that super powers will make Peter look lame with his spider powers.

One part of me says no yet another part of me says yes. I don't really know, I guess it is up to the writers. P:

marvel mary jane.

YES! YES! YES!
 
And anyone who says no should stop with their anti-change, keep everything iconic BS.

Mary Jane no longer Married to Parker because readers can't relate to a MARRIED Hero?? 
 
WHAT! Is that to say only single people read Comics/Graphic Novels!? Man thats BULL____! 
I got Married couples and boyfriend/Girlfriend reading together all the time. 
 
Ok OK...so these stories are to pull into the fantasy that anyone can imagine they are with these people or with these people, by making them untouchable...like Wonder Woman, Batman, James Bond etc. 
BUT we have character in these stories who are with children, married or married with children (not to call attention to the TV show). 
My only problem with Parker is, his life was unbelieveable. Unbelieveable that a person with that much lying (for protecting his friends) would still get the girl he's been chancing since school!  
I girl who is a supermodel at that. No I'm glad they are wrote them out, he needs someone more realistic. 
 
Superman has Louise, Batman has assassin capable women, Wonder Woman/Artemis have NO ONE cause they are written to be untouchable, that way everyone wants them. Which is why it always sounds bad when every they are hinted to pull toward someone or only pull toward someone in an elsewhere idea. 

I just want them back together and I open to the idea

I actually think Mary Jane could be a help to Spider-Man even without powers.  He needs someone on the ground who can be his info gatherer while he's out swinging around town doing the physical stuff.  Be his "Microchip" if you will.  And let her use some of the fighting ability I'm sure she's picked up over the years.  She could train with some of Spidey's friends.

She doesn't need powers but she needs some serious combat training 

It wouldn't hurt.  I mean, if she had super powers, maybe she'd finally have the ability to do what few others seem capable of and beat some sense into Peter.
 
"You made a deal with the devil?!"
 
*Insert roughly thirty pages of nothing but comic book onomatopoeia implying a rather lengthy and amazingly brutal beatdown.*

One Word NO!

I think that instead of superpowers she should become a bit like oracle. She could always be in Spider-man's ear and it would allow Spidey and Mary Jane banter throughout his battles. It would let her be a part of her life without giving her powers.

It'd actually give them something to do with MJ besides being "the wife" or "the girlfriend" and whatnot. That was one of the problems they had with the marriage, there wasn't much to do with MJ besides constantly having her life threatened. 
 
Also... what comic is that picture at the top from???
