Have you tried NPC_Tool, where you could replace any existing villagers with different ones of your choice (even you could put custom villagers)?

I used that DSPet great tool when I saw the new villager and wanted to choose a better one (from my viewpoint). And I used ACToolkit to move
that new villager house to the spot that I want it to be (switching the locations between the moved villager house sign with the new villager house).
