After the “cloning” bug is fixed, the next slated improvement for the NPC expanded feature is the option to turn them over to the local authorities for a reputation boost with that town.
Trying to make that system modular right now is going to be incredibly tough and involve rewriting half of that feature and creating dummy holds for the base mod for the features they pull from it, and most of the mod’s features tie together in some way. Hopefully that new option will address some of your concerns with the system!
