SUPER GALAXY Warwick and Super Galaxy Ornn Pleaze Rito

Ornn could possibly work, but Warwick not so much. Super Galaxy as a skin line is about mechas, but unlike the mecha skin line, the focus is on the pilot here as well.
Imagine it kinda like the power rangers, fighting super heroes who can jump into a big mecha if things get messy.
That means this skin line works best with champions who have some kind of pet or transformation in their kit, to showcase this piloting the mecha theme.
Annie and her Tibbers mecha
Elise and her spider mecha
Fizz and his shark mecha
Gnar and his Mega-Gnar mecha
Lamb and her Wolf mecha
Nidalee and her cougar mecha
Rumble and his Tristy mecha
Shyvana and her dragon mecha
Thanks to his ultimate, which lets him summon a gigantic ram, Ornn might work for that line (even tho he would be kinda strange with his personality). He could be the pilot and he is summoning his ram mecha, just like (for example) Fizz does.
Warwick on the other hand doesn't really work well. He lacks a component here. He could be the mecha, but who is going to be the pilot? Or he could be the pilot, but then he lacks the mecha.
I think a technology based skin could work for him, just not Super Galaxy. Battlecast or Mecha would be better choices for him here.
