Villager Rescue

Well villagers are completely pacifist NPCS, but they live in the world of minecraft, a world full of dangers where any carelessness can put them in a dangerous situation, their enemies the pillgers for example have prisons (the one in the Woodland Mansion), the point I want to make is why not add "captured" or "lost" villagers, they could be in the pillagers' prisons and spawn randomly in places far from villages.
They would have the same clothes as normal villagers but in a torn and dirty version giving the appearance of being isolated for a long time, when they saw the player they would start following him, if the player takes him to a village the "lost" villager will become a normal villager and as a thank you will drop some emeralds to the player.
