Repeating houses (especially successful/HotY-caliber houses), runs the risk of diluting the prestige of nostalgia. Successful houses are successful because of numerous variables that can’t be controlled even before the house opens, let alone years afterwards.
If anything, Universal would be better served to revisit house concepts that weren’t well received (“Re-nightmared” instead of reimagined). Jungle of Doom, Spawning, Cold Blind Terror, etc.
