I ended up testing this by adding a second one in an area I could recruit it but in Origin form. When I left the dungeon it reverted back to base PD so I set it so the Origin form can actually be evolved into. Which worked! It’s kind of a double edged sword since it still reverts forms at the end of the dungeon so to use the Origin form you have to evolve it between every dungeon. But it also means that to do it you don’t have to permanently give up the base one at least. If anyone else figures out how you’re supposed to use them normally though would still really love to know though lol.
