I honestly feel like if they decided to do a Conjuring maze, incorporating all films from the franchise into one attraction, they may cut parts, like this clip, out of it. That, or they may change the scare around, like they have for different IPs in the past, and basically use a blackout actor, maybe not in the same style as the spandex wall effects have been, but perhaps the same layout of laundry like that of Ash vs Evil Dead, but instead of a full actor scaring your by jumping out from curtains, have an actor press against the sheet quickly, triggering the strobe light and sound effect used in the clip. Not very revolutionary, but I feel they'd focus more on scares that have the physical characters from the movies, like Bathsheba, Valak, the crooked man, Anabelle's demon, etc.
I dunno, I still feel that Bedsheet scene is one of the scenes in the Conjuring that really stick out to me; that, "Hide-and-clap" and the witch on top of the cupboard are the big things for me.
I imagine a Conjuring maze is gonna be a Jigsaw deal where the final room is the Nun (if we're doing it this year) and then the rest of the house focuses on the other movies. I also think the maze can safely ignore the first Annabelle and just focus on Creation; it's made more money and gotten better reviews. Maybe include the opening murder (that was also in A:C) and then go straight into the farmhouse in Creation.
I think that the Saw location this year has enough space for a good Conjuring house. That maze was pretty amazingly long, all things considered. Focus on the main movies (if they can get away with it) and have a medium length Annabelle Creation section, and the whole thing should be golden.
Overall, this might be a little overstuffed, but here's how it might go:
(***=main scene
*=transition)
***Start in the Warren's trophy room
-Conjuring 1
***Bedroom with a 3:07 clock
*Black transition "Hide and Go Clap" hallway (Yeah, it's a black hall, but it makes sense here)
***bedroom with Bathsheba on the cupboard
*Transition hallway with the maid + the secret passageway
***Bedsheets! (Halloween '15, Ash '17)
*Turn a corner and you see Annabelle and the rocking chair
***Exorcism; Shotgun with an airblast
-Conjuring 2
***Amityville windows and seance
***Dark basement with Valak; Blackout sticks a log through Ed's chest (A la Freddy in the old mazes)
***Valak Painting!
*Facade!
*Living room as a transition; the old chair will be there, a tape is playing the "interview" with the Hodges daughter. Bill jumps out at the very end
*another hallway with the tent. The Crooked Man pops out!
***Crucifix room with Valak/Bill
*short transition basement
***Valak at the bedroom with the open window. Ed leaning out. Thunder and lightning.
-Annabelle Creation (maybe optional?)
***Annabelle Higgins and her boyfriend stabbing their parents
a la Prom Queen scene in Purge over at HHNO 2015 (first Annabelle)
*Outdoors Facade! Demon pops out of a well. The Scarecrow is there.
*Main foyer with staircase. Dead Mr. Higgins with the screwed up fingers. (probably won't happen; this might just be a plain hallway)
***Bedroom with cut-in-half women. Monster Mrs. Mullins with the creepy mask pops out. Demon pops out of dumb waiter.
***Annabelle's room. Annabelle is in the closet. Kid actor pops out and shouts "YOUR SOOOOULLLL"
-The Nun
***Dirty Apartment. Smells like dirty laundry and shame. Valak shows up with a five o'clock shadow, offers you a cheeto. You accept the accursed cheeto, because you have no inhibitions.
