I think someone should create a family add on

I have been searching for a family add on that would replace villagers with npcs that are designed to look and act like humans but I have failed to find any. this is my idea for what I think would be a perfect add on: Some of the npcs could have family’s small family’s or big family’s (it could vary) and you could make relationships with the family’s and become friends with any npc. but there would also be some “single” npcs that you could build a relationship with and move into a home together (that you built or an empty home that another npc already built that doesn’t already have a family in it) and maybe eventually raise a family together like get married and have children have children (and the children would be able to grow up and eventually have their own family. But I don’t think the children should grow up rapidly.) I have just been looking for Addons that make Minecraft more realistic and I think a family add on would be super fun for me and other players that are looking for the same experience as I am. And I would preferably like the add on to be for bedrock (because that’s what I play on)
