Cross-Over

I think it's time for another DC/Marvel cross over. 
Personally I'd like to see Taskmaster go toe-to-toe with Deathstroke 
& Captain America (Bucky) against Batman (Grayson) 
Would you like to see a cross over? If so who would you want 
to see fight each other or team up?  
What would you want the purpose of the cross-over to be?

never minded single character cross-overs. some of my favorites being Batman/Punisher:Lake of Fire
and Superman/Silver Surfer...but theyve nuked the fridge too many times on a Universe/Universe cross-over
to where i think they shouldnt try anymore. just seems to be a recipe for failure.

" @CATMANEXE:  It's been so long since a good cross-over. Imagine a cross-over with writers like Brubaker, Geoff Johns, Bendis and Morrison on it. The potential is endless.  "
