Kingdom Hearts II A Riku centered game?

I want a Riku centered game but if they do make one they will probably make it a side game or a like a completely off story game

 

Technically, we've already had one: Reverse/Rebirth. But that's just half of Chain Of Memories, and the other half is again Sora. I think it would indeed be a great idea to have a completely Riku-centered game, like what he's been doing in the shadows while Sora sleeps and Roxas is in the Organization. It could be similar to Days, but the quality should be better and hopefully you'd have the option to use it for the PS.
