I've had an idea on how to integrate Miis into Brawl for a while now, and I still stick by it. For near the end of classic 1p mode, you always have to fight a giant team of something. In 64 there was Fighting Polygon Teams, in Melee there was the Fighting Wireframe Team, and for Brawl I suggest the Fighting Mii Team. It's a generic character and all of them have the same stats and basic attacks of like punching and kicking like wireframes. They would read Miis from your plaza first, then fill up more from the Mii parade, then if there's extra spots still that are needed the game would have premade ones. Other than this though, I wouldn't really want any other kind of Mii integration.
