I talked with them as well. Seems like a neat idea. As they point out, however, the engines are not certified, so you would have to make the skymaster an experimental airplane, for engine development, which I would imagine would impose restrictions that most of us would not want.
Granted, systems and accessories would have to be changed. I don't know how you run a deice system from a turbine, but they do it on King Air's. Panel would have to be all electric, no vacuum pump (not a bad idea).
Lighter weight, readily available fuel, how can you go wrong?
