I'd like to see a version of this where you can send your kid off to learn to become a fighter,wizard etc.. Pay the tuition cost and they disappear from the game for x time and then come back fully grown and outfitted as an x with the ability to be a companion. However, the mod would have to account for time since game time is 1 hour per minute it would have to be a lot faster. Adoptable kids in Skyrim are roughtly 10-13 years old. Making them grown to say 18 would be 5 years game time or 76 24 hour days real time. Too long so it would have to be half or less. They would one day come back to the house and there they are fully grown and ready to join you in your quests.
