Very tricky is your problem. I amd not really sure about this.
I am just gussing.
one way to look at it is to register each DNS master server
as secondary DNS server of the other DNS master servers. But this
imply a lot of zone transfers between servers and probably a load
sharing problem and the time between some master goes down until
other start replying to request for it.
Another way to attack it is to put central NAT router/s. To which
all the DNS queries will be directed and the router redirect it to
the DNS master servers. You can put IPTABLES rules to match which
DNS master server should respond based on the DNS request IP segment.
And have ready scripts to check for the avaiblity of the DNS master
servers and update and flush the IPTABLE rules.
