Porter's Backpack Cosmetic Back Attachment (idea)

It would be cool if we had a backpack back attachment cosmetic that grows bigger the more items you have in your backpack. With indicators that shows weapons protruding in the backpack if you looted a weapon, and orb currencies falling off if you looted orbs a certain amount of currency orbs. I like the idea of more grounded cosmetics rather than glowy wings, or edgy looking capes. It would also be great for aurabots since most of the time they're the ones looting for the party.

I'm imagining the Metal Slug ammo girl - I love the idea.
