There's a good one for Meta Knight... Null Gray Fox. You have to use different models, but the models for it are really good (plus Spiderman, Power rangers, jedi, etc.)
For everyone else=YES
Though the enhanced versions by KingJiggly are really sufficient until stronger ones are made.
model replacements don't really count, as its another character entirely. as for me, I got zero two now. I haven't tried it, so I'm unsure if it has a psa or not.
