How about...

 (1) In each repository, run "repack -a -d".  That would ensure that
     everybody has the necessary objects that they themselves need.  By
     doing this for a repository that borrows from another makes sure
     pruning the latter would not break the former, so you start from
     leaves and move on to the repositories they borrow from.

 (2) In each repository, run "repack -a -l -d".  By doing this for a
     repository that borrows from another repacks the former without
     objects it borrows from the latter, so the former repository will
     retain what it needs but will borrow what are common from the
     latter, so you start from the repository that does not borrow from
     anybody else, and move on to the repositories that borrow from the
     one you already run this step.
