Any concept ideas on a new Kled, reksai, or illaoi Skin?

I'm just curious, But I was wondering if our Riot overlords have any skin ideas/concepts in progress for the champions listed above? It'll be neat seeing a underworld or Crimson Elite Kled. As for the crimson elite I was thinking skarrl has a darker skin tone while having maybe some blackened/grayish plated armor and Kled in a suit like how Riven and Talon's is. As for Rek'sai, I can see possible ideas such as a Molten/frozen and or guardian of the sands. Now for Illaoi all I can think of is a bloodmoon or deep sea one.

These champions have been out for quite awhile and need some new kicks. :Release dates: Kled: 08/10/2016 Illaio:11/24/2015 Rek'sai: 12/11/2014
