What kind of Chromas would/do you want next/

So this is going to come as an odd question to some, but what chromas would or want next? I'm someone who finds chromas interesting as they've vastly improved since they're initial release but never really has a lot of choices of them since most of them are to champs that I don't play or play a whole lot. Plus I think some people have ideas on which skins could work for chromas.

So what chromas do you want to see happen?

For me personally it's:

-Super Galaxy Shyvana -Mecha Zero Sion -Beast Hunter Sej -Battlecast Cho'Gath -Dragon Trainer Tristana
