I've not heard of it.

Actually, the cylinders, pistons, rods and crank from the Honda 1800cc
Valkyrie flat-6 combined with a aircraft style case would hit the spot
for fans of smaller airplanes. *However, it would still need a PSRU.

something like 260 pounds for 80 hp?

I wouldn't think so. The crank is light enough to use as a dumbbell
and that's heavier than the cylinder blocks. Just guessing of course,
but I'd say 180 lbs for 100HP which is better than an O-200.
