The pump and chopper might work, but it appears there needs to be some

Thus, if you don't isolate, it could wreak havoc. Since it looks like I
need the transformer to isolate, I thought I'd use it to bump the
voltage instead of a charge pump. But, if a 1:1 transformer is easier
to source at the right specs, I can look into a charge pump.
Yes, I could just power off from another location, but I'd prefer to
figure out a way to hand a good 9VAC signal to the 64.

Because the power source at hand is 5VDC @ 10A.
The 64 need 4.3A of
that, leaving a bit more than 5A for this step-up solution.
Chuck, frequency is 50/60Hz.
So, why not a charge pump to 10VDC followed by a 60 Hz chopper and
some RC smoothing? (Just thinking aloud and wondering if a lot of
iron is really necessary).
