Demon gnar, i like the idea of yordle devils.
But i would sacrifice it if it meant champions with like, barely 3 skins get a super cool skin.
Honestly they need to turn their focus to the community because i've seen some really good ideas.

I think of more Rek'Sai Skins every time Im asked to make a list.
Elderwood Chrome/Full Metal (even though she already has Aeternum. Not the only champ to have two robot skins before) Infernal, my personal favorite Dark Star (Shes practically the only Voidling without one!) Arclight Space Invader (Star Guardian enemy) Guardian of the Sands Earthrune (basically just Elderwood though) Demon Definitely Not Spectral Ironside Skin where she's a moving boulder/statue Gatekeeper/Underworld
Academy Quinn and Valor Arcade Quinn and Valor Beastmaster Quinn and Valor (Rift Quest skin line) Blood Moon Quinn and Valor Cosmic Quinn and Valor Elderwood Quinn and Valor Headhunter Quinn and Valor High Noon Quinn and Valor Odyssey Quinn and Valor Pool Party Quinn and Valor Project Quinn and Valor Pulsefire Quinn and Valor Resistance Quinn and Valor (Battlecast skin line) Riot Quinn and Valor Road Warrior Quinn and Valor Special Forces Quinn and Valor (Commando skin line) Star Guardian Quinn and Valor Super Galaxy Quinn and Valor Victorious Quinn and Valor
And, of course, Cockatoo Quinn and Valor for OCE server skin!
Old School Ziggs (more cartoony, black and white, cutesie skull and crossbones images on the bombs, smiling mines and all that)
Zytronic Ziggs (futuristic-y, with a Ratchet & Clank vibe)
I don't expect Riot to add anything like this since Ziggs doesn't bring in the dough, but I'm going to load his model up in Blender and take a stab at it (I can add it to my portfolio so it's not a total waste of time).
Honestly, I'd love to see a skin on 
where instead of turning into a Western style dragon she turns into an Eastern Dragon. (Serpentine and maybe with small wings and long front claws).
