I like Ziro's and Drae's Ideas.

It would make Avatars MUCH more useful, and more fun to control, having an "ally" fight alongside of you. Either by manually controlling it, or having it attack the enemy you have targetted, both would work and both would be really cool. The current way the avatar moves and attack isn't great for the way GK is - i.e. In Maps or on the Overworld.

I also like Majin's idea of the Avatar being stronger (More HP, Faster, Stronger, etc) in relation to your Wisdom level.
