That's what Junio suggests: chop the history by introducing an appropriate graft make it "permanent" by filter-branching (and remove from info/grafts). Now you have a disconnect dag. clone/push/whatever works on the "components" given by connected branches. Note that in this approach all history after the "chopping point" will be rewritten, i.e. get new sha1's.
