Hmm, I thought that was the point of adding the "-A" flag to git-repack.

Though an even simpler solution, since you control all of the repos, is to just temporarily add references from the "parent" of the fork to every ref of every forked child. Then do the repack in the parent, which should then contain all of the objects for all of the children, delete the temporary references, and prune in the children (who should see most of their objects now in the parent).

The only downside I can think of is that anyone grabbing the parent's packs via dumb transport will grab a few unnecessary objects for the forks. But presumably they are not all that big, being forks (i.e., there will only be a few commits, and they will be delta'd anyway).
