Should There be a 5th Rarity for Jokers?

My thinking is that all rare jokers aren't created equal. Some rare jokers are pretty good, and some are game-breakingly good. Nerfing is the wrong way to go, and buffing a ton of jokers throws off the balance of the game, so why not make an Epic rarity for Jokers like Baron and Blueprint? It would make it harder to get those insanely broken builds, but it would also make it more meaningful and exciting to find something like blueprint.

There are OP common and uncommon jokers which can be upgraded to higher rarities, and I think the same needs to be done for OP rare jokers (Just making them legendary would be lame though, IMO).
