That'd be awesome!
I'm not going to lie, I am a HUGE Waluigi fan, so my opinion is kinda biased in those regards. However, I have a question:
With the Waluigi over Pit, are you going to reanimate him to have more moves that would potentially suit an oddball character such as Waluigi, since I believe a number of that Waluigi's moves are just his assist trophy attacks? I might be out-of-date on the Waluigi PSA, however, so if I am you can ignore that question, and the following question.
Provided you are reanimating, I may not have the tools to do it, but I could possibly try to assist in describing some of the attacks he could have to you.
