A possible way for Riot's balancing capabilities to improve?

So in another game called Dofus, there exists a group of hand-selected players called "The Zenith Team." The purpose of these players is to discuss balance and how to fix the game with the designers. They are NOT beta testers. A way to put it is: They see the stuff that is being made, and help the designers test it while it is still at internal stages, and then discuss ways of making the idea better.

I think if Riot hand-selected a group of people from the game, those loyal players could see the early creation of various champions, and improve them. Because at this point, my trust in Riot is dwindling.

There, of course, have to be requirements. The person must be VERY knowledgeable about the game, must be very active, and cannot be toxic AT ALL. (I would say 2 or more years of never being banned) This group of people would be allowed to access the server where Riot has new concepts and are able to playtest WITH the Riot Employees and other "Zenith Team" members.

Thoughts?
