What about a transformer with 2 separate 9V secondary windings (not hard

This seems like the best idea, to me.
Agreed! :-)

Sounds like you just need a single 9VAC power supply,
a bridge, a
voltage regulator, and perhaps some caps to clean up the signal a bit.
The trick is to provide enough wattage.
No.
The 9VAC has to be a separate transformer winding from the one that

the +5VDC eventually, because of how it's used...
