Would this be a fair change to Akali?

When fighting Akali and you know there's a decent chance you're gonna lose if she jumps on you, all you can do is cast defensively and run and most of the time it doesn't matter because she uses all charges to gapclose and burst you. Would it be fair to make it so that she can dash to someone with her ult but she can't dash to them again under a certain amount of time (like Yasuo E). This seems like a huge nerf to her power, but maybe you could also add in that she can dash to them again IF AND ONLY IF she lands a Q on to them (doing so would allow her to keep going and bypass the time, but it would still consume a charge of her ult.) However Akali's Q CD is pretty low mid and late and being her main ability not a lot should be done to that UNLESS her Q is turned into a skillshot?
