Would probably end up being a Samus clone, and they're already Zero Suit Samus in there, so no don't think so
I like to think MegaMan would be an excellent addition to the, appearently, growing list of potential new characters. IF he's gonna be a clone, i think it would be more likely that he would be a Kirby clone, seeing how he's copying the abilities of his enemies.
But i still think MegaMan would have enough original moves of his own. Think about dashing forward or dashing in the air (like the dodge move but rather for outmoving someone).
