Going off that spec map, there definitely needs to be a IP from 2020 or late 2019, and I think it makes sense for that to be either Spiral or Candyman (or both)
I'd personally be excited for a Billie Eilish maze. I don't know if I'd call myself a fan (I do like some of her music) but I think it could be very exciting because we don't know what they would do with it.
I don't think Sabrina or Haunting make too much sense, I think it's a little late to use those IPs. If Channel Zero was still around and more popular, a house themed around Candle Cove would've been amazing, same with No End House
