Pretty Crazy Yi Idea- What if Part of his R Became a Passive?

With upcoming changes to Fervor further nerfing Yi (let's be honest, it's a nerf to Yi. He won't benefit from 60 AD more from 110 bonus on-hit physical damage with the way his Passive and kit work), I have a crazy idea that I wonder what the community would think. For the most part, Yi is almost entirely reliant on his R to do anything unless he is fed, which he relies on his R to become. So, what if part of his R became a passive on his R? Like this:

Highlander Passive: Champions takedowns reduce the current cooldown of Master Yi's basic abilities by 70%. Master Yi gains 15/27.5/40% increased attack speed, his movement speed is multiplied by 10/15/20%, and he gains 15/17.5/20% Slow Resistance. Active: For the next 7 seconds, Master Yi gains 15/27.5/40% increased attack speed and his movement speed is further multiplied by 15/20/25%. During this time, he is also immune to slows. While active, champion takedowns extend the duration of Highlander by 7 seconds.

Highlighted areas are what is changed, and crossed areas are removed mechanics.

What do you guys think? It would make Yi less reliant on his ultimate in order to do anything.
