Capcom actually did it. Phoenix Wright is in Ultimate Marvel vs. Capcom 3, and somehow Capcom managed to build an arsenal of attacks based on Phoenix's strengths: investigation, gathering and presenting evidence, and ... getting out of Maya Fey's way.

He even has a super attack in which he presents decisive evidence in a murder case against his opponent.

If you're at New York Comic-Con, you'll be able to get material for your own testimony about this game by playing the new build featuring Phoenix.
