the Nobodies essentially have no purpose, and really wouldn't do much other than attack anything they came across. Heartless are different, as their purpose is to steal Hearts. Nobodies don't even have that. So, unless you have a powerful Nobody, such as on par with an Organization member, then they will essentially be irrelevant.But yeah, interested.

Nobodies if left to their own devices would probably go after heartless, trying to find their hearts. There are less nobodies than heartless though, so without somthing leading them people probably wouldent see them all that often. Motivations and such aside, they're probably just unnecessary unless they have some relation to the story causing them to be around. 

Anywho, possible interest. Keyblades should probably be limited if too many people want one, but at the same time keyblade wielders shouldn't be more important than other characters.
