I think there was one, but it sort of died out. I'll repost what I said there:
The pipe dream is Bloodborne.
Other than that, besides what people have already said,
- The Cornettos Trilogy seems like the perfect cult classic property for a maze. I know Shaun of the Dead was a SZ, but I want a maze, darnit.
- Black Christmas (OG or new remake) seems like the perfect smaller IP to look at for one of these years
- Hill House sprang up out of nowhere and became a huge sensation out of the blue, so I'm sure the HHN people are looking at that one. TBH, I'm very surprised they didn't get it for this year.
- Audition is one of those cult classics that had a huge profile at one point in time, for just how effed up it was. I'd love to see it at Horror Nights.
- Channel Zero got cancelled, but I'm always holding out hope for a revival, and that show's got characters galore and enough name recognition through the Creepypastas, I think, for a maze.
- Oh speaking of cancelled, Hannibal would also be tight. I want a maze full of Mads Mikkelsen lookalikes
- The Ring is something I'm surprised they haven't done yet. Characters present a problem, but they could take inspiration from the creepy videos itself, especially the man with a bag on his head.
- On a similar vein, The Grudge would be awesome.
- Oh, actually, Kayako v. Sadako: The Ring vs. The Grudge. Cuz why not.
- House (1977) would probably never happen, but still, it would be insaaaaaaaane.
- Outside of J-Horror, Hitchcock is something that keeps coming up and I think they oughtta do it soon, because the conversation around Hitchcock has started turning sour due to the abuse he heaped on his stars. If they don't want everyone to feel weird, they should probably get that one out of the way quickly.
- Salem's Lot is getting a big, glossy remake by James Wan and that's probably something Uni is looking at.
- Jacob's Ladder would be amazing, with tons of mirror effects and creepy masks. Pipe dream? Probably, but still, I doubt it's any less obscure than Trick R Treat or Killer Klowns.
- Buffy the Vampire Slayer I originally thought was owned by Fox, but apparently Dolly Parton has a production company called Sandollar Productions that owns the TV Rights to the movie, so they could get around things that way.
- I Know What You Did Last Summer is getting a TV series from Amazon with James Wan writing, so something to look out for.
