Your schematic has lots of diodes even after the voltage doubler.

Could some of those be left out?  Are they there in case the code goes wild?

What do you think of adding a third PWM voltage supply for VDD instead of regulators
for supporting PIC24, PIC32?  Especially since you have no stock of PCBs
now, a hardware change would be easy.
