Sorry, I don't follow.  "History" here means the sequence of revisions
where the file was modified, right?  If so, then past revisions are
already frozen in the repo's DAG, and each revision there is
immutable, right?  IOW, if a certain revision changed only file A,
there's no way to retroactively change it so that it appears to modify
both A and B, right?  It is also not possible to add revisions that
were not originally there, right?  So what am I missing?
