Option to see all champions that friends have obtained Level 5 Mastery with?

I know this is a rather optional and unneeded feature; however, in addition to the new Mastery system, I was wondering if a future patch might allow us to see a page in which we can see all the champions that our friends have reached the level 5 Mastery for? At the current moment, we can see the top three mastered champions on profile pages; yet, after that only the champions with below level 5 Masteries are shown.

Not all would be interested in this feature; however, I think it would be neat to see and show the champions that all of us have mastered in. Many of us have our favourite champions, and I think it would be neat to show off more than our top three used champions. :) Just was wondering if such a system might get implemented later - regardless, thanks for reading!
