Uh, "git rebase -i A", change "pick" on line "C" to "squash". This should have the same impact as what you are trying.

One way you can insert this is:

  git rebase -i A^
  change "pick" on line "A" to "edit"
  delete lines "B" and "C".

  when it stops for amend, don't amend.
  git apply --index pat
  git commit -m "my new B and C"
  git rebase --continue
