There was a Turbine Luscombe or something like that kicking around

There still is. It was built by the Luscombe Foundation here in AZ.
It's a classic example of why turbines and small low flying aircraft
are not a good mix. The 150 hp turbine burns about 16 gph in cruise.
With the Luscombe's small fuel capacity, range is pretty miserable.
The only incident I've heard of with the plane was... wait for it...
fuel starvation!

All in all, it's a very interesting exercise in design and
engineering, but as a practical mod, it's a flop.
