  That should work just fine. In fact, we are doing exactly this same thing
(the master for cfc.com slaves for chrysler.com and vice versa).

There used to be a bug long ago where data from subzone secondary files could
be propagated in zone transfers of the parent zone and vice versa, thus
creating "immortal" records which would persist even after being removed from
the master, but this bug has been fixed for a long time.
