Two attractions in that plot would be interestingWhat if it is the British MoM complete with it's grand lobby.
The VR Broom attraction is Auror Training. You go into the the small Auror's Office where 8 "Brooms" are waiting. Hop on and put on the VR goggles. When it starts the wall in front of you magically dissolves, and off you go out of the building on a Death Eater treasure hunt through 8K London.
The second attraction would be The Trial of Fenrir Greyback and take place in Courtroom Ten. It would be the "puzzle theater" patent and basically be Universal's version of ExtraTERRORestrial Alien Encounter but with a big scary werewolf AA in a cage in the middle. Of course something goes wrong and all hell breaks loose. It would be a mix of practical and lighting effects including some projection mapping.
I'd be super impressed if they could pull that off
