Yeah, I remember that from the actual Xan mod and it's actually the one I used. But there is definitely an option for it in Level1NPCs. Now I think about it though I think it may have been the Tutu options (it has options for Montaron and Xzar also for instance).
So yes, there doesn't seem to be any current modded-NPCs in there but there easily could be (quote from the L1NPC page):
