Well Cloud I don't think would be as universally wanted as... say the Black Mage. Plus why not just put in Terra (the main character from Final Fantasy VI)=??? She is literally the same character as Cloud, just not a whiny little girl (which is odd, because usually the female character is the generic whiny character), easier to relate to, and starred in a game that was actually on a Nintendo console (the Super Nintendo/Famicom).
Regardless, I still think the only Final Fantasy character with a chance is Black Mage and Chocobo, and I don't think they have much of a chance. However, Slime (the mascot character of Dragon Quest) I think does have a chance, given that canon (and numbered) Dragon Quest games are again exclusive to Nintendo consoles.
PS1: Speaking of which, sooner or later I need to get Dragon Quest VIII (I played a demo of it and absolutely fell in love with it, and haven't gotten around to getting in in the past 7 years) and Dragon Quest IX.
PS2: Anyways, later y'all, I'm hitting the hay.
