I think Monty had some ideas for doing this, IIRC it was discussed at the
meeting in Barcelona in January.

If what I remember is true, it is actually just that a 5.6 master refuses to
replicate if the slave does not say it is configured for MySQL 5.6 GTID. The
slave does not need to actually _use_ GTID. So I think Monty's plan was for
the MariaDB slave to just lie to the master and say that it's a 5.6 slave with
appropriate config.

And the MariaDB slave would need to recognise and ignore the new MySQL 5.6
events, such as GTID.
