Also, I've been very loosely kicking around the idea of WCW vs. nWo Mafia, just because it popped into my head a while ago and the possibilities are hilarious. Not something I'd do for Season 4, though.
EDIT: Posting this got me thinking about some more possible roles. Oh my god. I don't want to say what they are, because the more I think about this the more I feel like I have to do it.
EDIT #2: Also, if I do this there are probably no more than two people in this community that will get the jokes, but that's fine with me.
