Oh so doing it without the set equipped works? unlike the rest of the upgrades?

I didn't science it myself (I just left the purple gear equipped while I was working on other characters, and when I switched back later the masterwork was unlocked). But I have heard that you don't even have to have them equipped - once you do the activity (e.g. killing 10 powerful enemies) on another character, it unlocks the masterwork for the character that already has the purple.
