You do eye tracking studies on the current league UI? Where, when, and how? If you think team frames aren't useful, let me point out the immense amount of utility that most MMO players, including PvPers, get from team raid frames. If there's an observed lack of use of your sidebar, maybe that's because it's in the wrong bloody place. Eye movement to get from action-to-sidebar and back is too high, even if the sidebar has tons of useful information I could benefit from.
If you have trouble thinking up how to effectively present that data, maybe you should rethink your career path, because I certainly can. Add two more light buttons to the side of the portraits, color code them for summoner spells. Allow the frames to be moved around. Change the brightness of the portrait of a champion depending on how close they are to you.
Your logic for player utility is flawed, as well. Colorblind mode didn't exist for a long time because "only colorblind players would need it, and they're a tiny minority" and then once implemented, many players found the color changes useful even if they weren't colorblind. A change for a minority actually helped the wide majority. (watch some streams if you aren't convinced)
To be frank, just go ask a WoW PvP forum what the best UI mod(s) are, see what features it has, and start to include them in League.
