A silly question! Of course there will be crossovers (at least player generated ones).
Plenty of scope for The Others beasties & baddies to easily become patients' delusions (or are they..?)
I see the same happening with a whole host of other miniatures - bound to be rules developed for zombies and many Lovecraftian beasties (from Mansions of Madness or Cthulhu Wars). I may even add some of the Doom baddies.
It may be harder justifying some of the Lobotomy enemies into The Others, but sure it'll be possible for at least some of them, e.g. The Antichrist.
I can't remember when Lobotomy is being delivered, but I hope to play this before The Others
You'll be lucky!
Lobotomy is due August 2016, The Others is before then (March 2016).
