Could there be more things available for switching from the Calamity Salvager? For example, the once amazon exclusive sets?

All my characeters/alts have this maid outfit and not all of them are female. I find it kind of a waste letting it hog inventory space just to be thrown on a retainer or something. It would be nice if I could swap it for the butler one.

Apologies if this as been brought up before, but as far as I know, the maid/butler ones are the only ways with a gender lock from amazon events.
