With a wet wing, you'd get hot wing anti-ice capability and a skin

in the bargain.

Couple years back, someone did a pretty good set of calculations on that.
If you captured 100% of the engine waste heat, It wouldn't be even close
enough to de-ice a wing.

Turbines do it, cause they burn tons of fuel. IC engines don't come close.
