There is a sentence in here that concerns me: "while using the MD-3's 400 Hz windings to deliver 60 Hz"
Because frequency and waveform are a function of generator speed, you would (theoretically) have to slow down the generator considerably to get 60Hz out of it. Couple this with having to slow down the engine, and you're running so far down the torque and horsepower curve that it's horribly inefficient. And that's if the regulating system would tolerate it as well. If it's inherently (self) regulated, it won't work. You need the speed to create a large enough magnetic field in the windings to saturate the fields. Kohler used to sell 180 Hz sets that were packaged with concrete finishing machines. Every once in a while you would have an end user who picked one up at an auction, not realizing what it was. Of course they couldn't use it to power their house unless they were using nothing but incandescent lighting as the load. "Can I just turn down the speed?" Many of them found a second life working for the state and local departments of natural resources - for shocking fish. They would put them in a boat, drop some wires into the water, run the genset for a prescribed time, and lo and behold, the surface of the water would be covered with (stunned, not dead) fish!
