3rd DNS server different zone files from 1st & 2nd NS

hi,

is it possible to have 3rd Name server different settings from 1st and 2nd DNS server?

meaning :

Primary and Secondary name server zone/settings/records
www.mydomain.com IN CNAME mydomain.com


3rd Name server zone/settings/records
www.mydomain.com IN CNAME go.publicredirect.com


Is this possible?

i have this idea for failover system.
if apache and NS1 and NS2 is down, the 3rd NS will take over
