That's an interesting idea. Seems to me it would double the leak rate,
and the failure rate, but it may be worth it for easy maintenance.
Not necessarily double. Since only one of them has to be in operation,
they would, when alternated regularly, only accumulate half the duty-hours
each.

Planning an SF story? :-)
