There is no easy way to hook this into the recursor; what you could do, however, is to arrange this idea within a PowerDNS auth backend (luabackend, pipebackend come to mind). Once such a backend script has been written, this setup could be as simple as 'launch=gmysql,pipe' (or gmysql,lua) where gmysql provides all your local changes, and lua or pipe fetch anything else from your upstream server.

Kind regards,
