Yes, on the or part: If you change a commit then all commits "after" that one (in terms of DAG connectedness) will need to be changed: each contains a "backpointer" (to the parent commit(s)) which is changed. I'm a bit confused: You rule out rebasing but don't mind recreating a new repo. So repo size is not a problem, is it?
