Idea to add more shadows to Shadow Assassin Kayn

My idea simply is this. Give more shadows to Kayn. The 2 choices I came up with are either make it so Kayn's Q leaves a shadow either where he casts it from or where he lands (one or the other) and he can cast his W from there. Disclaimer: A second W hit would do partial or possibly no extra damage, but would definitely increase the slow. A second idea is to scrap the Q idea and make it so when Kayn uses or ends his R, a shadow appears and acts exactly like his Q shadow in terms of the w. The only difference is, Kayn will be able to cast Q and the shadow will also dash to his cursor a short distance and slash just like normal Q. Since Kayn's q has no bonus effects besides being a dash, it could do say 50% damage if it ends up hitting a second target. These are just my thoughts, as personally being a Kayn main I feel as if his assassin form is only strong when played into no tanks and barely any cc, so these changes would make him just a bit more viable.
