If the Paldean Elite Four got unique rooms, how do you think they’d look like?

I think we can all agree that it was one of the letdowns of the ScarVi games that this E4 didn’t any unique rooms, given the unique rooms of previous E4, even if they weren’t as individually unique as they could’ve been. I mean, the Paldea Gym Leaders had some interesting battle arenas in that they were actually battlefields and not just inside a building, so why can’t the E4 for the Paldea League get some unique battlefields? So, brings me to the question on the tin, how do you suppose the unique rooms of the Paldean Elite 4 would look like?
