Third Plot Idea for a fourth movie

My third plot idea for a possible Poltergeist IV would be to do a completely new story-line revolving around another family with a ghost-problem,with some link to the first three movies,like the family moves to the same area,or even the same town, Cuesta Verde as the one from the first movie and the same ghosts haunt them,or one that has no link,with a totally new town, settling, as well as a new family and characters.The pro to this idea is that you get to put, or add new,fresh ideas to the series,but the con is the audience might get put off if you don't have some link to the first three films,and some also might be put off that you're not adding to the Carol Anne Freeling storyline.So,do you all like this idea,or no?

Second Plot Idea

This idea would actually be a prequel where it is explored about the back-story with the Reverend Kane and his followers and what's the cosmic link between him and Cuesta Verde and the Freelings,as many movie series are doing prequels now and this would be able to explore the back-story more.
