This is like saying that a car manufacturer could start making flying cars without any of the factory workers noticing except those operating the machine that bolts the wings on. PCB manufacturers do not *have* any machines for sandwiching chips between layers. It is not a normal PCB process. I think all the factory workers would know about a brand-new machine and completely different workflow.
