Wow, you are making me miss the Charm spell from Morrowind. I got NPCs to live in my house by Charming them, but in Skyrim, I think you'd need to hit someone to make them angry enough to follow you into a new cell. You would then probably need Pacify to calm them down, then quickly paralyze them before they leave again. There is a limit of how far an NPC will chase you before giving up, and you'd probably have to experiment with it, but I doubt they will travel through multiple external cells.
Another way is to enter your house while someone outside it is speaking to you. That makes them enter as well, but then they will immediately leave. You are also restricted to only those who travel past your home. You could also get lucky with pathing issues. I've had Valindor and Wujeeta both walk through Honeyside on their way home from work in the evening, as they enter through the external door and travel out through the town door. I've also had a courier do this.
For the people living in your home I'd get them to be a follower and take them out of the house somewhere and tell them to wait. That way they won't be around to attack whomever you bring home. A spouse could also be temporarily told to move to another house as well. (Always pays to have multiple houses as a Vampire, just ask Dracula.

)
I have never tried this but I think you can just pick pocket the poison back out of their inventory if you want to revive them. I think you've given me something to mess around with in my game.
