I honestly don't think they need to keep the cult gimmick but, if they do still have a "leader" going forward I would make it Brodie Jr. Keep the family involved. He doesn't even have to show up on TV if the family doesn't want to. But you could just have someone mention that -1 sent instructions and do that. I think it would be something neet to do and that way you can keep Beodie Jr. involved and hopefully happy.
