Ideas for Mastery 6/7 Rewards

I think that the rewards for the current mastery system are a little bland. Sure a Badge and an emote is cool, but what if we had a summoner icon for the champion we have mastered. Think about it, wouldn't it be cool if we just had our Mastered champion's face as our summoner icon or better yet maybe even skins for the champion. Obviously that would take a lot of work though. But my final thoughts are, us league players should be rewarded a little bit more with our hard earned mastery points. <---- Just wanna see this face as my summoner icon
