Sounds cool yo. I also wanted to do something like that. Have you seen 's Ultimate Fighter roster thing? I wanted to do something similar to that, except for the Manly Mens roster, including a short bio, basic info, their opponents in each round, and when they got eliminated.
Alas, though, I don't know if it's possible....yet.
But what do you mean yours would be a collab? Like you and someone else? Or EVERYONE draws their own character?
