I don't think there's a native way to play back all the changes as a
rebase. If I had a dire need to do as much, I'd do a little
do/undo/diff/patch tango, something like

:w current.txt

then undo to C1

:w c1.txt

then undo once more take you back to the pre-C0 change and save that:

:w pre-c0.txt

Then, in the shell

$ diff -u c1.txt current.txt > rest_of_the_changes.txt

and run that patch against the pre-c0.txt

You might be able to use git to checkin various points and then
use its rebasing to help you out.

But in pure vim? Not much.
