Well. If I was the lazy me, I would just copy PM Wolf's Attributes over him.
If I was the super me, I would strive to search in the PM PSA what's causing the L-cancelling in the Guard SubAction, the AirDodge and such. I would also change a few moves to make him more competitive.
It's easier than it seems though. But I don't say it will look 100% legit though.
The first option does seem easier, but what do you mean by PM Wolf attributes? Do you happen to know what files I would need to mess with in Brawlbox?
