to think of anything else.
I might be talking c**p here and this uber-redundancy scenario isn't the
intended way for /altroot to be used. Otherwise I'd be very interested
and grateful to read any ideas anyone has on the subject.

I think if you need that sort of redundancy you just use a mirror RAID.
Boot encrypted mirror RAID is supported (man boot(() and man bioctl(8)).
I suspect you could use installboot(8) on the disk holding your /altroot
to make it bootable, but I have never tested such a thing.
