Yeah, you’d essentially need to turn them into the trait equivalent of legendary weapons. Something that you don’t build your playthrough around when you start it, but an exciting surprise when you do come across it.
Could be quite a bit of work for something you might never see so it’s probably pretty low on the list (if it is even on there), but it would be a really cool thing to have happen to your merc while playing.
This is also pretty much why I’m really looking forward to the legendary weapons. :D
