Pokemon Idea... Pumpkaboo + Litwick

Litwick and Pumpkaboo (real pokemon)

I drew this idea for new Pokemon, and I honestly cannot believe that Nintendo didn’t come up with this on their own. 

Some Pokemon, like Escavalier and Shelmet, evolve by swapping parts of themselves with other species of Pokemon as they are traded. Sort of a symbiotic thing.

Anyway, there’s a candle monster, called Litwick, and a pumpkin one, called Pumkaboo. They each have separate evolution lines, but I had an idea. What if they evolved in that armor-swapping way?

I envisioned the ghost part of the pumpkin escaping and evolving into Flygeist, as if it were a ghost flying away from the pumpkin it escaped from.

Then, a different ghost, Litwick, gets trapped in the jack-o’-lantern and becomes Pyrepatch, a fire / grass type. I drew all of these pictures, by the way.

 
How cool is this idea? Nintendo, if you’re listening, please take my idea and use it (no permission, reward, or acknowledgement required! Just use my idea!)
