Please add some use to cosmetic duplicates

You know, one of the most dissapointing experiences in the game has to be seeing that golden star icon on the map just for you to realize it’s just the Siren’s Call weapon trinket that has dropped for the tenth time this week.
Having duplicate cosmetics was never fun in Borderlands, particularily the ones you get as quest rewards, but with Bl3 having so many of them and even legendary ones it just got worse. Also, the worth of any an all cosmetics seems to have been reduced to 1 $, meaning that any of the white rarity weapons that also dropped for you is gonna be more useful and valuable.
Please, let us do just something about it. Make them sell for some amount of eridium for instance.
