Choo Choo Sion Skin

So I was discussing with my friend about a skin which has a concept to where 1) Sion looks like a Train Engineer 2) Sion looks like a train. And the skill we were thinking of when we thought of this little idea was his ulti of course. As he's starting up his charge he can be making the traditional choo choo sound as he gettings closer to the end of his spell. I mean this is by all means just an idea I wanted to throw out there before forgetting about it lol
