Tell us more about this in-line generator. This is the first I've heard of
it and it sounds interesting. Is it a commercial product? From whom?

Don't know the dimensions of the generator in question but one of the
design goals was to change as little as possible, so the distance
between engine and gearbox was unchanged.
Off the top of my head, the rotor is 1.25" deep, and would need a 6" dia
flat on the engine side of the gap, centered on the shaft. The stator
fits completely inside the rotor, so it only needs 1/8" to allow for
routing the wires out. If the space has been expanded even a small
amount, it should allow for a relatively easy addition of a compact 38A
generator, eliminating belts and pulleys. I only have a microscopic
amount of time on mine, but it has been working so far.
