Powerpuff Arcade skins?

So with the release of arcade riven the collection is complete! Riot has successfully made the powerpuff girls in league. I first noticed when a friend of mine commented how the three (sona riven and miss fortune) look incredibly young in the new loading screen. Then I recognized their colors, that's when it hit me! Don't believe me? Look below.

I also think it's kind of funny how riot made them similar in character to that of their respective colors.

Miss fortune - blossom. Leader, strong determined and thinks things through. (Like all good marksmen should she plans things out and is often a leader.)

Riven - Buttercup. Tough hotheaded tomboy, serious and no time for planning. (As such riven is tough and rushes headlong into enemy teams.)

Sona - Bubbles. Soft, sweet, and often smiling due to her innocence but she is in no means a pushover. (Like how Sona is soft and sweet to her allies, but a huge pain to the enemy team.)

c'mon riot, be more original.
