did you try dnsmasq?

On first query, dnsmasq ask all dns servers the answer and elect the fastest
as the main server.
This continue indefinetely.
If at one time, the dns server timed out in a query, a new election is made.

When all servers are down, dnsmasq still could resolve names from
resolv.conf
