Look at any other haunt and ask why wouldn't it be possible. Some mazes use their infrastructure on purpose (anything in Parisian) and are planned that way (or if Knotts, the Mystery Lodge where Grimoire is now). But imagine if the reverse happened. A tent maze is then relegated to Parisian. It now has to account for an outside sequence, a hallway courtyard, and a very specific ending that spits out into French street. Essentially, the middle of the maze is most affected, but everything else would probably stay the same or similar.
Now think of the opposite. The space is now bigger. Why not take off the roof or push back the walls to extend vertically? If designed as a tent maze, there are specific hallways designed for scareactors to go through to get to booholes and what not. Again, I get it. But now you have the ability to open everything up. Just take up double the space. Does that mean longer hallways and more wood? Does that mean more scareactors? Ofcourse, budget will always be an issue. But it's absolutely purposeless to utilize a soundstage and give it only a quarter (if that!) of it's space.
KSF has warehouses that you can tell they use every inch of that and those mazes feel much longer, bigger, and taller than HHN (in particular scenes). KSF mazes are a bit more confined in their pathways (maybe 15-25% thinner). But also, these warehouses are only 1/4 the size of any given soundstage. A soundstage maze should be INSANE. The facade at the least should be massive. AvP and Weeknd are the only ones to really go crazy in that aspect. Why is the Weeknd the first time they've ever put someone on a platform above the maze? And it wasn't even done well?! There's been so many soundstage mazes at this point, how has the experimentation not gone beyond that?
