This isn't what you think it is, that title is probably a bit misleading. Sorry!
First, what I'm actually proposing has more to do with shops. Currently, if you have replaced your server/singleplayer spawn shop, there is no NPC trader from which to buy NPCs. Either we need a guide on how to create an "advanced" shop with the NPC trader or we need a system in place that lets us do that.
Secondly, making the first issue worse is the fact that we have no way of spawning NPCs: there needs to be an admin command making this possible.
