Mastery 7 Champion Icons Idea

Right now as it stands when you get M7 on a champion that you main you pay (insane ammounts of) BE to validate that you have performed well on a champion. I would argue that this isn't very rewarding nor is it SUPER satisfying. Sure emote spamming over a dead enemy whatever, but if you are say a one trick, then that is just another day in the neighborhood for you. After a long time of thinking about it because 1 champions specific m7 skins/chromas would likely take too much time and effort and is already an in game thing (because you already have the Mastery Emote) I reasoned that every champ should have an M7 Icon. A unique unlockable that you get when you upgrade a champion to M7, that shows the champion in a semi-realism fashion (like when Jhin got his cinematic how his mask was basically HD the greatest and arguably coolest champ teaser (not including Senna because I mean a fight scene is a fight scene AND THOSE ARE DOPE)). I think this would be a nice touch because some people really like a champion but never get lucky from the Mini-series icons, or their champ doesn't get skins so they never get skin related icons ( ) And perhaps as a sort of special effect when they use the champions base skin + the m7 icon they get a special alternate Realistic HD splash art (similar to how champs from the original cast got special splashes on their base skins).

I am aware this would take time and I'm not saying NEXT PATCH FFS, I am simply asking because I really like the champions (especially the ones I spend so much time grinding to m7 on) and would think people might like this.

To any Rioter who sees this, is this a possible future feature or is this too much to ask for? To the community as a whole, what do you all think?
