Hah that sounds pretty neat accually, i like the idea!
Another idea i came up with was a 'tailor' package or 'be your own hatter/creator', the person who wins gets to design (as in decide on how it looks like) a new upper or mid or lower headgear (not sure if the player should be involved picking the effect or not but depending the sprite of the headgear the GM's could list a few options the player could pick its effect from once the sprite is created). After the sprite is made and the effect is decided the player who designed it gets some exclusive time to wear it before it gets publicly released.
