Elementalist Yasuo? (He already has wind) & Snow day Azir??

First off, yes I am biased about this considering I love playing both these champs mid-lane. But let's be honest, it does make sense. Secondly I hope to be making art of this sometime, just gotta wait, so be patient please!

Yasuo already has some pretty awesome skins: Blood moon, project, High noon! Considering he is a master of wind already makes him pretty freakin awesome, but wouldn't it be interesting if a legendary skin featured all the elements? Fire, water, Wind, Earth. And this is pretty easily possible. His (Q) steel tempest, his blade hit would be colored different when he slashes. There would be fiery tornadoes, water spouts, whirlwinds as usual, and dusters. Pretty simple, and no having to change the size and shape of his tempest at all. His blade would glow depending on the color of his element, like his project skin does, and his armor could do so similarly. His (W) Wind Wall could be a wall of fire, a wall of wind, a wall of water, a wall of rock. His (E) Sweeping blade would have just a trail of fire, or a trail of water, and a trail of earth; you get the picture. His (R) Last Breath would be insanely cool, seeing him pop up his foes and slashing them down with the power of the elements. For fire he could light them up with fiery slashes. For Water it would wash around him as he slices it though enemies. For earth he could slice with a dark brown glow, and when he slams his foes back down the ground would tremble underneath causing small cracks and stuff. The possibilities are endless with this.

Azir being one of the hardest champs to learn in LoL makes him not as played in season 7 so far, and he hasn't been much of a power playing champ (one effecting to solo queue). Although he has gotten a warring kingdoms, and I know Christmas is far away again, I think the idea compliments him to perfectly. He is god of the sand right? Well why not god of the snow? His Passive could summon a giant Christmas tree as a star shoots out Christmas-like beams at champs. His (Q) Conquering {Snow} Will be able to send his snowman or penguins or whatever you want to make for his soldiers as Christmas towards the champ. Snow slows you down as well does it not? His (W) Arise can just summon up the minions from the snow, and considering the maps become snowy, during Christmas, it won't seem like he sends them out from nowhere, even though it would be that afterwards. His (E) Shifting {Snows} Will do the exact same thing, just in a snowy effect. His (R) Emperor's Divide will blast towards and army of snowman shields-man or penguins holding shield. His look could just be colored differently to a more snowy look. and His staff could be of a snowflake center.

So these are just idea, I will draw them later. Comment and vote what you think! Thanks for your time.
