How much would that suck during a GPS approach to minimums far away from
the
crisis? Would WAAS stations be shutdown to?

You might be surprised at what happens if you lose RAIM inside the FAF
anyway.

If you lose the navigation radios on any approach (and it can and will
happen with any sort of approach) then the best thing to do is climb
immediately, maintaining course to the MAP as closely as possible, then
flying the missed approach procedure.

If the GPS system is shut down then you can expect to break off any approach
and revert to radar vectors.
