Or a N-chan FET on the "bottom" side ? Might be easier
to interface to the PIC ?

Or just using the *internal* FET of the PIC output pin and
connect the divider network directly to the pin ? The
current is so low that the PIC will probably drive the
resistor network to a few 10's of mV's from 0, not ? The
PIC could switch the divider network on/off when needed.
