Could we protect against that by running a capacitor between neutral and
earth? If active and neutral were swapped, you would get current flowing to
earth which would trip the RCD (are these mandatory now? I know some
legislation went in recently in WA making it so).

All the low voltage components would be powered from USB, so those
components should be safe.
