(I didn't notice other than his swords are blue, since his outfit is otherwise obscured/discolored by the Nosferatu smoke.)
Uprising was most definitely inspired out of what Brawl did bringing Pit back into the spotlight, though. "May" contribute, indeed. I think MK's Mach Tornado was also an original thing at the time and then ported into Super Star Ultra. Not coincidentally, however, Sakurai directed both of those games just as he does the Smash series... I'm not sure other games/franchises not under his direction are taking design decisions directly from Smash.
