Two companies - Disney and Warner Bros.

There have been made countless (it seems) movies and tv shows (movies from Hollywood) about each. Eventually people are getting tried of these and people say superhero burnout. They remade/re-released/redid the universe and plan to do multiverse stories.

One story I know in comic is called Marvel vs DC. There Batman, Green Lantern, etc. meets ironman - avengers. Would it be possible for Disney and Warner Bros to team up to do this comic? Will it be animated or stage? How much will it cost?

So many questions if it can be an idea.
