MGX DC MARVEL 2012 tournament HELP

I just downloaded the Marvel vs DC patch, and was completely blown away by the way in which the characters looked. I really wasn't expecting the characters to be so cool looking. In fact, I like them so much that I'd love to start a new offline franchise mode with them. The reason why I need help is because whenever I load the marvel roster it messes up a lot of the names of regular players. I think this happens because the Hulk exceeds the maximum height and weight limit that 2K allows. I was hoping somebody could edit his character for me because I have no idea how (I would do it in game, but he engenders an adverse effect on the regular roster as soon as he's loaded). If there's an easy way in which to do this I'd gladly try myself.

Thanks in advance.

Actually, I don't think it's possible. The problem doesn't seem to be caused from just the Hulk. Is there a way I can get spider-man in association mode without it changing the "normal" roster? He's my fav., character out of the bunch.
