A brake would still be needed on the prop, and the clutch plates would need to have spring separators, to make sure the plates separated when the clamp force was removed.

The Sikorsky X-wing clutch design, scaled to size, would work just fine.
Raider's prop is just a foot or so from the YT706 exhaust, so it likely always spins, by design, to prevent excessive heating on the prop blades (if the prop were braked).
"X-Wing"... there's a technological dead end we haven't heard of in a long, long time.
