Reading the first page and the last page, it looks like this has turned into something yet MORE convoluted and complicated than the AOS, but maybe there's more to it? (Or less, Haha? )

aos vents the crankcase and heads for reasons detailed in my other post. body of the aos is a swirl chamber designed to separate the liquids from the vapors. the 'head of the aos' is the diaphragm noted in my other post. the diaphragm connects to the intake.
aos diaphragm can break, failure can be catastrophic if your engine ingests oil and hydrolocks, aos is hard to get at and replace.
the porsche god is keeping the original aos in place, disabling the diaphragm in the aos (blocking that vent) installing a replacement diaphragm (a vag piece) in an easy to service location and adding a catch can with a sensor as a failsafe.
