Could a Jigsaw structure be used to make structures that villagers builld?

I would like to create a mod where villagers will check the number of beds, and then the population of the village and if there are more villagers then beds they would checks if they have the resources to build houses. if they have the amount needed to build a house they will build a house on the outside of their town along the road. They would also be able to upgrade houses if they have a certain number of resources. I would like to do a similar thing with professions. If the amount of farm lands is not sufficient enough to increase the population, then a farm would be built if the resources are available. maybe have a townhall block which adds resources from the entire village based on the occupations of the villagers and any livestock or crops present in the village and everytime the player trades with a villager will add the amount traded to its inventory. If you buy bread from the farmer the emeralds you spend will end up in the chest. If you sell wool to a farmer the wool will end up in the chest. The idea would be to  give trade an actual purpose other than to just give the player emeralds. a wealthy city would expand as it becomes wealthier as more people will want to live there.
