@Riot Rewards for Champion Mastery 7?

Do you have any plans for a champion mastery 7 reward? Right now it's pretty much "if you're playing as the champion, you get a bonus thing to BM with" which isn't very... rewarding. Like, maybe a special chroma you can buy for IP/RP if you've got the champ to tier 5/6/7? (like in Heroes of the Storm) Or maybe giving us the champion's portrait (like in Heroes of the storm too.) Or maybe the champion's abilities as icons?
