I'd honestly hope for the opposite. I get that it's already been 5 years since Ghostbusters was last at HHN (Dear god 5 years
), but I think Frozen Empire would be a lot more visually distinct from the first house with it's iced over New York and more varied locations. It would also still allow for fan-favorite characters and locations like the OG Ghostbusters, Slimer, ECTO-1, the firehouse, NYC Public Library with the Lions and Library Ghost. Seems like the best of both worlds personally.
The new Ghostbusters headquarters with the containment units is what I hope to see. Those ghosts had some fun designs that weren't utilized very much in the film itself.
