Mod Idea

Hey I had this idea for a mod where you can make a village, well that's basically it on one sentence but let me explain. You can craft a house selector that allows you to select bounds of a house then when all 4 corners are selected it counts it as a house. Therefore villagers are able to come settle down at your village. But the only way for you to get people are from explorers wandering around with random traits, wants, and needs! Depending on these they may come back or settle down in your village (only if there are houses with at least one bed add more beds for more people to live in a house but only if they are related). So let's say you have a village of normally happy people with low water needs low food and want a very social village and a wanderer comes by. Lets say hes a grumpy person with high water needs and medium food needs as well as he wants a calm village with not much noise. This means hes most likely to not settle down instead hell maybe go talk to some people buy from the shops and then leave never to return now let's flip that. He's the opposite but he has medium food and water needs. But he likes the village its just the water and food he doesn't like. This means he might come back every once in awhile barter hang around then leave repeat. But what about if you don't have house marked? Then this means they will come by for a day or a half and try to barter with you once or twice then leave. The only reason he will come back is if you live near a cliff or something like trees, a mountain (determined by how high a group of blocks are) or just have a lot of livestock around. If you like his trades or something you can make a house and mark it. If they like the scenery or the amount of needs/wants matches them and suits them then they will highly likely stay. I can't script but if I could script this I would because I honestly think this idea is pretty cool.
