Ultimate Skin Concepts

With the season coming to an end, I was wondering if Riot was thinking about a new ultimate skin? If they are, I have 2 concepts that I believe have potential, but function differently but the other Ultimate Skins.

Soul Devourer Kalista

• Instead of changing forms every time you level your ultimate, the skin changes for every certain amount of kills you achieve.
• When you kill an enemy with this skin, Kalista absorbs their soul, changing models after absorbing enough.

I thought of this skin while watching The Pledge. Kalista is the perfect champion for a skin such as this because she gains power with each soul gained from a pledge, and I believe Riot can easily pull something like this off. There is, however, a second champion that matches this concept.

Keeper of Souls Thresh

• Similar to the Kalista skin, only with a different method of changing.
• Instead of changing with each point put into your ultimate, you change depending on how many souls you collect. For every certain amount of souls you collect, the model will change.

I believe Thresh has the potential to pull of a skin like this, and it perfectly matches his lore.

When Thresh absorbs souls, or Kalista accepts a pledge for a soul, they both increase in power. As a result, these seem like perfect ideas for these 2 champions. Tell me what you guys think, and try to get Riots attention!
