This sounds like a use-case for changeset evolution with
hidden-but-retrievable commits:
https://www.mercurial-scm.org/doc/evolution/index.html
With that you can rebase and have linear surface history, but the
rewritten commits still exist as hidden commits with references to the
commits that superseded them.
Problem: It not possible with Git. It would require switching to
Mercurial — which would also enable useful abilities like coordinated
rebasing in a group: https://blog.disy.net/hg-evolution/
(and which is GPLv3-compatible)
Best wishes,
Arne
