Well, all of this could be done already, although not very automatically.. Whenever a new mail is delivered or user is logged in, the user's last-login timestamp in SQL could be updated. And replicator's userdb iterate_query could return only users whose last-login timestamp is new enough. The SQL userdb could be used only by replicator, everything else could keep using LDAP.
