Should Kingdom Hearts drop the idea of using FF characters in the games?

[Furore]

A few Dragon Quest characters would be awesome. The thought of Yangus alone in a KH game is making me chuckle. As far as FF characters go, it seems to serve the series well so far and as long as they don't go overboard with characters I can't see myself disliking FF characters in the games.

Though they didn't seem to do Setzer justice in KH2...

I always enjoyed the way the two worlds clashed, Disney and FF together who would have ever thought of that before KH. Not to say that it has to be done with Final Fantasy characters, they can just as easily make all new ones. Just gives you a sense of knowing the side characters without having to develop them at all. I think that adds something to the game. Either way they do things I wont be upset though.
