Waggle control in One Piece: Unlimited Adventure

Namco Bandai is getting ready to release One Piece: Unlimited Adventure later this month. In the game you can play as eight characters: Luffy, Zolo, Chopper, Nico Robin, Sanji, Nami, Usopp and Franky with a glossy cel-shaded coat. Control in the game is simplified to shaking the remote to make Luffy punch. On one hand shaking the controller makes One Piece: Unlimited Adventure easy to play. On the other it’s not much different from hitting “A” over and over again. How would you change/improve One Piece: Unlimited Adventure to better use the Wii’s control set up?
