MCU & DCEU Movie crossover?

If Marvel and Dc made a crossover movie, would it suck? Also what would be a good fight between some characters you'd like to see on screen?

The tones would really clash, one is waaaay more lighthearted than the other.

A good fight might be..no clue.

I'd like to see a Thor-WonderWoman movie if they were definitely going to do a crossover.

I'd rather a crossover comic, but if they did do a movie, I would like them to make fun of the clashing tones.

Like the Avengers could go to DC Earth and it's always cloudy and dark.

JL can go to Marvel and everyone is happy and cracking wise.

Batman crossing paths with the likes of Iron man, Cap, Bucky, and Black Panther would be interesting

They don't even make crossover comics anymore. I wouldn't be interested in it.

The Comicvine space-time continuum would collapse
