Fright Done seemed to only have it for 2016. And that I would imagine it could happen, with chances higher if the film gets distributed by Universal.
But, we're talking about a film that doesn't have a solid release date, nor a proper distribution company that we know. And that Ouija and Split, have barriers that I don't think would lead well for HHN in business matters.
Honest, if Blumhouse V2 happens for Hollywood, I would expect Purge and Halloween as definites, with another Universal/Blum IP to round things up.
