I think it would be awesome to have the ability to design your own gear. Like being able to design your home and stuff. Maybe like being able chose different part of your chest piece from long lists of different presets or gear you already have. things like making a fur hood and clock, low cut vest, tight leather, soft silk, metal, chainmail, different symbols on them, color combos. But keeping with lore so nothing like batman suits.
Maybe its just a bad idea so whatever.
