We need a Marvel vs. D.C. game.

I've been tweaking Marvel vs. Capcom 3 ever since it came out (Deadpool/Wesker/Taskmaster.) And the more I play it, the more I wish there were some D.C. characters in the mix. I mean the series is called "Marvel vs.", so why not vs. the other major Comic universe? Now note I'd like DLC to be free, but since the characters don't fall under either universe it wouldn't make as much sense to include them in the core game.
