Strangely enough, the thought of me about if ST becoming a house now (as I have two episodes left..); I would have to imagine that they would have to focus more on the Supernatural elements of the Upside Down, the creature Designs, and the town itself. You could pull select characters; but you couldn't replicate having the kids into the house due to logical reasons.
I'm not saying that it can't happen, but I think we need to wait another season so we can get more environments and characters to play with before they try to do something for HHN with the concept, as it should be done in some way (especially the Upside Down).
