Creating an AI for this game would be incredibly complex. The amount of moves possible combined with the amount of things needed to be factored in for each of them really makes it quite unrealistic for such an indie game.
What could be great, though, is an easy way to tell uke to perform X actions in X mod. Just like in the fight vs uke practice thing, but for longer custom segments. So, you could practice sparring against an opponent doing moves for a longer while, as long as you don't touch him.
