A reasonable Hecarim nerf idea if he would get nerfed again

I was just thinking about what if you were able to cancel 's E if you manage to stun or knock him up? It doesn't really make sense that someone continues charging at you after you completely stop him for a second. Of course the skill would get a lower cooldown, just like 's Q. He gets away with not picking flash, because no matter what the jungler and the laner does to him, he just gets faster and faster to run out of the lane. The nerf wouldn't really matter in teamfights, since he has an ult to avoid cc and get to the backline. If the charge would get this meaningful counterplay, he would be able to get buffed without getting too strong. Please share your thoughts about it with me because I'm no Hecarim main, not a big top laner.
