Idea for a mastery system

Okay, so it's not really a mastery as it is a way to BM more in game. clickbaited What if you could use twitch emotes as a mastery? Like, if a sick play happened, you could flash a PogChamp mastery above your head? This could work for a few of the emotes, and you could charge RP for them and I would buy them quicker than I could feed a bot lane.

Maybe they already addressed this, it is kind of a stupid idea in a way, but it would help spice up the game a little rather than just having a chat of people rolling their faces across their keyboard to show how sick your play was.

Thanks.
