I suspect the failure rate of a single correctly specified diode is many many orders
of magnitude lower than a mechanical switch. And you can parallel two, three
or four such diodes if you wish.

This and another post suggested diode isolation.
Trouble with adding elements to our systems is they too have failure modes, downstream
effects, etc. Diodes can and do fail open and fail closed. So, we have
to put them in the Fault Tree and Failure Modes and Effects work, estimate failure
rates, and see if they help or hurt for forced landings and dark avionics
suites. Have not done it yet, but might yet.
