That leaves the Cessna 172 as the only obvious candidate for which anyone
might certify and announce such a prop. Remember that the major prop
manufacturers are primarily in the business of certified props for
certified
engines which qualify for single engine night and IFR flight. It has been
done before; the Cessna 150 received a Clark-Y prop, which was regarded as
a
fairly new improvement, shortly before it was replaced by the Cessna 152.

I am curious, but not holding my breath.

Fair enough. Go for it, then let us know!
