It would be kinda OP on Kayle I think. She already has good AoE with her E, so Hurricane would give her a lot of AoE damage. Also, with Hurricane, she would become the best pusher in the game at late-game, no matter if she goes full AD or hybrid. The only thing that would bother me would be when E deactivates and she goes back to melee, but then again, that is annoying anyway 
Also, Kayle's E is a modifier, not an "autoattack spell" like Sivir's W or Gangplank's Q. Hurricane should work on Kayle the same way it works on Jayce, Nid, or Elise.
