I mean, we already have armor sets in Eververse as crossover stuff. Wouldn't be too far fetched to consider an "homage" content update (not DLC like Renegades) as potential candidate. Just to be clear, I speak about inspired weapons, not an inspired story. As much as I love Mass Effect and surprisingly enjoyed Renegades despite huge concerns regarding IP integrity, we shouldn't overdo it with external inspired IP DLCs, Bungie.
