Well yes that will work (assuming an electric drive train with a
battery) , long as that APU produces significantly MORE power than
the average that you will need at the prop hub. The reason why you
would need MORE power is to make up for the losses inherent in the
generator, motor, battery, and controller.

Also, I forgot to mention that I'm a professional
designer and illustrator, formerly with Lockheed-
Martin. Within this electric airplane concept which
would sustain these very long ranges with an RTG,
is a series of conforming "mini-tanks" which encapsulate major
electrical components. Holding no more than 5 gallons
total, you top them off with liquid nitrogen. This
cryogenic sealed system effectively turns your electrical
system into a zero-resistance super conductor. Control
surfaces are best facilitated with servos and fly by
wire software.

This may sound a little exotic, but other people have
verified the plausibility and science behind it. A
home-build isn't out of the question. With generator,
super conduction, and fast charge NON-lithium batteries,
the range may really be how long you can sit in a seat.
