[Ben 10] Is Ultimate Alien X a possibility or is that form already as evolved as it can be? If not, what would ultimate Alien X be like?

I imagine Ultimate Alien X would be a unified mind with the same reality warping abilities. 

With X, the limit isn't its power, but the fact that that the strength is locked behind the dual personalities that prevent any actions from taking place. If that barrier was removed, then Alien X would reach its Ultimate state, and thus become literally unstoppable.
