Perhaps once you do a turn in, you should be able to summon that tier again at will, ala T10 armor scripting. This would prevent such crazy problems, and with UW lore it wouldn't allow you to have more than 1 at a time.
Hell, epics and all armor should work this way. This would allow people to correct their own problems from bad combines, glitches, etc.
Great idea, but probably a fair amount of work. I think its probably easier to just go in and reset a quest for the once in a few years someone decides to delete a UW. most other mistakes are trivial.
