If it was a join-effort, with AM2 doing most of the work, I could see something good coming out, but just 'taking pointers' I don't think would make a big difference. It might, but I'm skeptical.
Considering how casual friendly their last two games were, I couldn't imagine how broken and unbalanced a fighter would be. Sometimes that doesn't matter to casual play, but at the same time, we don't want something that's not even fun.
