don't know if they would do that, but it would be a good idea. a lot of people remember Wario being in his original get up (like most of my friends), so giving them the option of playing as the version of Wario they remember most would be a plus.When you alternate costumes do they fully change? For example: if you change Wario's costume would you be able to switch to the original one?
as for your "who's faster; Metaknight or Pit?" question, I would have to go with them being about equal running speed (since Metaknight glides along the ground for his run, insted of useing his feet [on a side note, I think his mid-air glide might be an air dash]), with Pit being a little faster. in terms of attack speed, I would say Metaknight for obvious reasons, but weaker then Pits attacks.
