LVL 8 Mastery rewards Idea

Could we get like a banner (the same you used to get back on the old client when you had an ultimate skin icon) for every champion you get at mastery 8? Basically, you get a champion to mastery 8, let say okay, for each class you have a special quest before getting 5 S+. Since he's an assasin he'd get special assassin quest. Once you complete everything you get a unique Zed icon and a very cheap unique Zed skin(not a must). You can get like a gold Zed name thingy next to your name when you have the icon equipped? It'll be super cool and people would like to do these kinds of quest to show off their mains, once you go on their profile it's the basic Video that plays on their profile if they have the icon on.

If you guys have any ideas I'd love to hear them out :D

PS: I do not main zed >:(

PS numero 2: BUFF FIZZ!
