A problem that is evident at once is 10.2 GTID events can not be handled
by 5.6. So at least some filtering should be devised.
To that part, maybe

 mysqlbinlog --read-from-remote-server=10.2-"master" | filter | mysql-client-to 5.6-"slave"

could be practical?

True. Cross-vendor replication check is very involving.
