Why has Epic not started selling blueprint skins yet

I am baffled at how they would add stuff like SHOES to the item shop before selling blueprint skins. It just feels like such an easy slam dunk I seriously don't understand it. Just Imagine stuff like a Magneto bundle with an included blueprint skin where instead of bringing out a blueprint and a pencil and drawing on it to build you place one hand on your head in focus and close your eyes with the other hand extended outward and do a summoning motion. I think that would be EASY MONEY for Epic Games and it would be something players would all probably get on board with fast asf. They dont even have to be that high effort either, I'm sure people would buy a simple reskin for a couple hundred Vbucks. Again it just feels like such easy money and something people would want to me I don't understand why they don't do it
