If jumpers aren't reliable, it seems possible to have different 0 ohm solder in place jumpers, or something.

If there will be jumpers, is this an opportunity to buffer the inputs with an analog mux?
This is likely a bit more complex part than is needed, but it has a minimum quantity of 1

If the voltage goes out of range, the magic smoke is released from the Mux instead of the dsPIC.
