Is it possible to make an enemy faction structure datapack?

Hello! I have been working on my own separate datapack that adds in various fortified town and city structures to the game in modern versions. This led me to looking at older mods like Ancient Warfare 2 and I have realized I could try to make a similar experience by making a structure datapack that uses Minecolony enemies to populate the structures, thus making some different kingdoms and nations for the player to war with. Does anyone know if there would be any issues with this? I figure I would just need to spawn the npc's and treat them like any other entities in a datapack, but maybe there is something else to it given how they were mostly made for raids.
