You could use the fuel as an engine coolant in a liquid cooled diesel
like
the Deltahawk.

With a wet wing, you'd get hot wing anti-ice capability and a skin
radiator
in the bargain.

1960's vintage Allis Chalmers crawlers using the diesel fuel as a
cooling
medium and working medium for the torque converter. Worked well.

would a mazda/wankle-rotary run on Jet-A, JP-4, etc?

If it did, it would come the closest chance of having waste heat deice the
wing. Wankel engines do not have a high enough compression ratio, I
believe.

The other issues have been kicked around before.

1.) Wings make poor radiators. The boundary layer of air does not move
enough, to carry the heat away efficiently. It was tried, even in the
early
years of air racing.

2.) Internal combustion engines do not produce enough waste heat to deice
a
wing, even if 100% of the exhaust heat and engine cooling heat was
captured,
and put onto the wing. 100% will never happen, and that makes the
possibilities even more unlikely.

Seems counter to say that a skin radiator won't cool an engine but won't
de-ice either. Last I checked, ice melted at 32F and coolant is usually
180-200F. If the skin radiator won't transfer heat to the airstream, it'll
get damn hot. If the heat won't melt ice, it's going somewhere.

I'd bet a 180F wing would melt ice pretty damn well with an OAT of 28F.
Actually, the golden air age racers with skin radiators worked pretty well.

BTW, if heat won't transfer through a wing boundary layer, why should it
transfer through the boundary layer on a cooling fin?
