Unless your photos are made for your grandchildren only, I don't believe
in a personal "dead" long-term storage. Most people I know just want to
keep files that they use at least occasionally.
While I like your proposal for long-term storage, I rather stick with
harddisks or flash drives for personal data. That way the files remain
usable while being archived.
But I wouldn't recommend more than two harddrives. With current hardrives
I regard it as sufficient to use just one dedicated backup disk or even
two copies on different computers. As long as the backups are verified,
the probability of two simultaneous drive failures is low enough to make
the risk acceptable.
And if the house burns down ...the shoebox wasn't fireproof either.
Back to encryption, I see no problem to simply use crypto filesystems
with this scenario.
