They could always do their own creative take on it, there are options:
A. In the house we see everything through Nikki's eyes as she's possessed by the Willow.
B. First half of house is through Bear's POV and 2nd half is through Nikki's.
C. The house explores locations not seen in the film, such as the One Wish Willow HQ, the area "Normal Nikki" is being held captive in, etc. This option could also further explore the backstory and lore of the One Wish Willow, and could also end with Bear burning in Hell or being tormented for all eternity, which I know would please all the fans of the film.
So, there are definitely ways they could make this work. If they just wanted to the events seen in the film verbatim, it would absolutely work best as a Horrors of Blumhouse room or two, but HHN tends to be insanely creative, so I wouldn't say a solo house is necessarily off the table.
