As cool and interesting as that would be:
Yasou's tooltips are pretty long winded as-is and he already has a ton of power in his kit.
From having to deal with Tryndamere/Yi never being viable melee carries at the competitive level I can understand why Riot made Yasou the way they did and how powerful simply having 550 AA range is, but it doesn't change the fact his kit seems a little unfair, overloaded, and over-complicated.
Yasou is also sitting at a pretty ideal state of balance ATM. He's not game-breaking and 100% pick/ban but he still gets picked and sees occasional pro-play, which is where every champion ideally should be with perfect balance. Giving his wind-wall additional utility would quite likely push him over the edge into a must pick/ban champion.
