Skin demo

Since they added the one time skin use on ARAM why not do something similar on SR? Pay 100 or however much RP to try a skin for one game. Say you pay the 100 RP to try out a 975 skin after the game you'll be asked if you want to buy it, if yes then you pay the remaining 875 RP but if no then oh well. I know you can watch videos on the skin but playing a skin yourself and watching a video are two different things.

EDIT: To prevent abuse there is a limited of one use per skin. So you can't use a skin 5 times and still only pay 500 to use say a legendary skin 5 times.
