Not sure if can even be attempted. If turns out to be a phenomenon that originates in a sub-Plank's scale then "machinery" isn't something conceptually possible there.
If consciousness, or any phenomenon that effects our physical world in a way we can perceive, originated from some mechanism that takes place on a sub-plank scale, then I think that it would be conceivable for some super advanced machinery to be able to effect or even replicate said phenomenon. Just not with our current level of technology
Well, semantics are stretching at that level a bit because while at sub-Plank it would still be technique/technology involved, I'm not 100% sure it can be called machinery. I don't discard that it could be machinery at our newtonian scale that creates an environment where that ultra-micro thing happens tho.
