It can be synchronized, and would be especially easy with turboprops that turn at a constant rpm (blade pitch changes speed). However, the changing geometry of the nacelle/blade position would necessitate a special setup. Beyond my pea-brain but I guess those geniuses at Crane could pull it off.
I know that I would sure be scared if I had to make the system work....this plane seems a bit flakey to start with even without shooting through the props.
