No, that would be OP like Wukong. The main reason Wukong is so powerful is his high AD scaling, and I think he is one of my least favorite champions to play against. When you consider champions like Shaco or Twitch, you see that the assassins and dsp carries (like Miss Fortune) scale with AP. Playing them AP is viable but not recomended, as they tend to be weaker and less useful. At the same time, can you imagine if Twitch scaled with AD? He would be unkillable.

The point of the abilities is to give CC, not high damage. The Ult gives you high damage while the abilities let you use it, balancing the champion nicely. So no, I shouldn't change the bonuses to AD. He would be insanely OP.
