I mean, I agree the M3GANs should get a permanent spot if they (or a similar act) were to return, and it could be put by a FNAF house to promote Blumhouse, but there is no way they don't give a horror property as major as FNAF it's own house. With the pairings they've done in the past, neither movie had the popularity, anticipation, or generational appeal that FNAF has.
