That PVC elbow and flexible tubing on the AOS looks creative, but I know that tube is a b!tch to replace. If it seals well and resists the heat it could work, but I'd recommend whoever buys it replace it with an original while the engine is out.
*I have a washing machine drain hose currently connected from the other side of the AOS to a catch can on a non-street car, so I'm not claiming to be any better.
