>>5426751nah, that doesn't fit both the theme of 40k in of itself, and in universe the people most likely would be severely against it. in this sense it would most likely just be seen as untasteful by other mechanicus adepts.
instead, i propose that we take someone who otherwise has already become a vegetable, someone from the hospital ward on our ice moon, and actually give them further purpose by taking their brain, and using it as a hiding mechanism for what would seem as a bodyguard to Rane. it being more so the forwarder of mechanical signals that we send it than the actual calculation center in the robot. this would work alot better in masking us to the rest of the mechanicus who don't trust machines without humanity in it.
i know our AI would hate to do this, because it's likely seen as a immoral thing to do, like, really immoral. BUT. it's the best way to begin forwarding out influence whenever Rane goes out to talk with the cog boys in the rest of the imperium
image related, possible robot design, for this puppet with a brain facade.
