Purchasable Menu Animations

I think it'd be neat if menu animations where purchasable and interchangeable, and potentially even downloadable after purchase. I had this thought when the Project Yi menu animation came out, which I really like. I like Yi as a champion, as well as the features in the menu animation, and would be really interested in buying menu animations that I could set whenever I logged on. I'm sure others would agree, it'd be a great bonus for players and additional source of revenue for Riot Games. If it didn't work out, the feature could always be removed, but really, what harm can be done??
