Riot, why don't you make more skins representing champions in an alternative universe?

Let me explain... There are two skins we have: Void and Underworld

The first shows how it would be if Fizz was a Void champion, despite him being from Bilgewater. The second shows how Wukong would be if he was a Shadow Isles champion, despite him being from Ionia. Another example: , despite being a Demacian champion, has a Noxus-themed skin.

Why don't we have more champions skins that shows them being from alternative places?

For example... What if was from Freljord? What if was from Demacia? What if was from Piltover? If I recall correctly, Void Fizz was a fan-suggested concept that most of community was wishing that was released.

There is actually a concept that I would like to be released... Void . What if she instead of a Gitterlance, had a "Void energy lance"? If instead of squirrels, she transformed enemies into Voidlings? If Pix was a -like instead of a fairy?

Speaking of void-themed skins, there is a recurring concept on Deviantart of a Void-themed skin:
