You should be able to take an armor set with the golden symbol on it and 'dismantle' it or trade it in for a token. That token is what you could use to trade for different armors. Depending on what it is, it takes a certain amount of tokens to trade-in. For example, you could get something like the Exiled Master set for one or three tokens while a set like Resilient Warden or Sith Recluse would take three-six tokens. To prevent people from making this a monopoly, you could get a warning message saying that trading for a new set would result in it becoming bound.
