I'm not sure if taunts have been discussed to this level, but I wanted to suggest something that I think hasn't been mentioned (to this extent, anyway.)
I think the taunts should get a makeover. Instead of a taunt that virtually does nothing (with the exception of Luigi), I think the taunts should be expanded so that they prove useful. For example, let's say Peach does a taunt that can heal 1% off of her current percentage (maybe she blows a kiss to the audience or something), or when Mario grows large, he can temporarily walk around and stomp enemies. The possibilities are endless.
I also think the taunt could be a move to increase your audience approval as well. Maybe the audience can choose a favorite and a less-favorite (and the less-favorable fighter who is doing the worst can get a tomato thrown at them every once in awhile.) I think with the audience on your side, can perhaps increase your speed or stats.
Instead of using this in regular matches, it could be a separate mode?
