My initial thought would be that it was not the best idea. I do
think it could be made to work, with the right aggregate,
reinforcement, and moisture barrier.
Others can chime in, but my biggest concern would be how water would
escape if it ever got in there.
Not addressing that issue, but for water barrier (to prevent it from
getting soaked with ground water), perhaps you could use one or more
of those vinyl outdoor billboards that you can get for free some
places. You would also need to make sure that the blocks were
completely dry before you used them, since best case they would only
have about 1/4 of their surface area to allow vapor to escape.
I would say that a small experiment would be to dig a hole large
enough to build a 4'x4'x4' model and monitor it for one of your
rainy / stormy seasons.
