Mastery 8 Idea

Ok so i've got an idea on how to properly obtain Mastery 8. The idea is that you are required to have Mastery 7 (of course) but instead of having to get tokens by 4 S+ games. I propose that you need at least 100k 0r 250k mastery on a champion; once that goal is achieved you can proceed to further the mastery of that champion to 8 by paying a certain amount of Blue Essence. whereas the normal costs to progress are now around 3950 for Mastery 7. I suggest the proposed Blue Essence cost be about 5k or 10k BE.
