The only one of these I could see being completely out of the question for HHN is Animal Actors, just with how tight that area is already.
HMU opening as a plussed version or just used as a meet and greet space would be great.
Bourne could just run its normal show during HHN and I think it would pull people in (did T2:3D ever run during HHN?)
BMG - I guess they use this for Grinchmas now? I feel like they could still use it for an HHN show, with a quick turnaround to Grinchmas after the event ends. How long could it really take to tear down one stage set and put up another?
Terminator would run when it was newer/early 2000s.
HMU could always do a "Blumhouse Presents" version with whatever synergy goals they have each year.
If WaterWorld can do Purge at night, with the same tricks/effects utilized during the day, Bourne can as well.
I understand why they want to avoid using Sinbad or TL theater for Grinchmas (daylight bleed), but those 2 stages get dark enough for lighting and I don't think it should hinder HHN.
