Diesel turning a generator?

Why not just turn the rotor with the diesel? Too obvious?

It *might* be possible that diesel-electric system would be lighter than
pure electric or pure diesel.

A small diesel could be optimised to run continuously at its most
economical RPM, producing only a little more electricity than needed to
drive the rotor in level flight. For additional power, electricity from
the battery would also drive the rotor. When descending, the battery
gets charged faster.
