That's really the only thing I can see working. There's no point in having a bunch of not-Batmans running around, and it would be just as silly if everyone were Batman.

Except I don't think most players would want to play as generic thugs. Of course, the game could let you play as the supervillains, each with their own powers/abilities. That might be cool but it's still more of a gimmick than anything else and wouldn't really keep people playing for years.
