Yeah, posted without fully reading your post, and explaining.
The issue with clone brains is that they don't even develop the ability to control automated processes, like heart beating and breathing.
Without those developed, the clone would fall out of the chamber, flop a bit, then die. (thanks for the description, Kane)
Doesn't matter how good of a pilot program you have if the brain does not have the connections to even control the heart and lungs.
You can't throw a car stereo into a car and expect it to play music without plugging it in.
Yes, you could replace the brain, spinal column, and the internal organs to bypass that, but at that point, you might as well use a walker with realistic features.
Now, brain-dead individuals, like coma patients, would work for conversion into biodrones.
Problem here is biometrics and DNA samples are going to go straight to someone that shouldn't be moving.
Next thing you know, your biodrone is being hunted as a shedim.
And if they connect you, ugh, say hello to, at the very least, a healthy bounty on your head.
G-Men and an open contract on your skull at the worse.
