If the machines are air-gap'ed how does the slave kdc sync to the
master kdc?  If the KDCs can talk, then you are not air-gapping.

A real air-gap also implies separate DNS servers, so just use
different zone information for the Kerberos SRV records in the outside
zone vs. the airgap zone to point to the air-gap "slave" kdc.
