I was thinking about setting up appropriate hook for that...

...but it might have been also done "manually", i.e. by having maintainer[*] do something like 'git pushall' to push to all distribution points (public git repositories), including Subversion repository, when pushing from his/her private repository to public repository/repositories. Maintainer would fetch (pull) from all leaf repositories, including Subversion repository. This means that SVN repository is both leaf and distribution point.

[*] I wonder if "The surgical team" idea (less known than "The mythical
    man-month" aka 'assigning more programmers to a project running behind
    schedule will make it even later') from seminal work by Fred Brooks'
    "The Mythical Man-Month" is still valid.  The 'surgeon' would be the
    maintainer / code reviewer, and would be responsible for merging in
    code from other developers.
