In-browser skin showing can be an idea?

So, as a lot of us probably know, there are some skins out there that have pretty cool splasharts and not-so-cool in-game looks. This could be really deceiving, since most of the skins in the shop have, admittedly, pretty awesome splashes. So what if when selecting a skin, it could show up on the Champion Ability screen instead of the original skin?

Like, say I wanted to buy Tribal Ryze, but I wasn't sure how it would look in-game. I could select the skin in his pull-up menu, scroll down to his abilities, and instead of seeing the default purple skin, then I would see the Tribal skin. While this might mean that a lot of stuff may need to get loaded onto the client, and the update might be long, I feel that it would be worth the wait. No more having to waste a refund on a skin that you don't like!
