change, transform convert branches to bookmarks

[Uwe Brauer]

Hi

I usually prefer named branches over bookmarks because I understand the
graph better. However in the current world most people use git and if I
want to collaborate with them I need the hg-git plugin, which works
fine, but requires to use use bookmarks for branching not named
branches.

So the question is: is it possible for example by using «rebase» in a
clever way to transform a repo such that the  named brances are replaced
by bookmarks?
