New Idea for all champions

This might not be done and even if it's done not put in for a long time but here's one of my Ideas to make League of Legends a little better without effecting Gamepley.

Customisable taunts,joke,laughs, and Dances.

They could be sold in the game store for ip/rp.

I mean idk about others but the only reason I play yasuo is so i can use his /dance to play his wind flute. Stuff like that I'd love to use on my other champions. Maybe have Warwick change his /taunt to simple animation where he howls at the moon before going on the prowl .
