Did you try to "zpool import -o readonly=on" and using TXG rollback?
If your drives wrote crap during disconnection, it is possible that
some previous ZFS transaction is (more or less) consistent on-disk
and was not overwritten.

You might want to back up ZFS labels of each disk somewhere, because
a rollback import clears knowledge of TXGs past some number (i.e.
CurrentTXG-10); it is possible you'd want to recover that label and
try a different offset into the past.
