yasuo assasin skin suggestion

it would be awesome if yasuo had an assasin skin, similar with Assasin Master Yi, im thinking of his outfit to be black and his nose and mouth to be covered with his muffler but black color and about skills effect, some black theme just like blood moon yasuo or high noon 3RD Q different colors, this would be black, and about his CTR + 3, what if he whistles and his CTRL + 2 when he spit wather on his blade also he should remove his mask.
