There's nothing to stop you configuring that local nameserver to use 
your two "backups" for names that it cannot resolve.

You could then leave the two backups in /etc/resolv.conf but if your 
local nameserver is authoritative for your local domain, then you 
probably want to know if it goes away, and those backups won't be able 
to look up names in your local domain.

I'm making some assumptions about why you set things up this way in the 
first place, and I may be wrong, but there's too little info in your 
post to give definitive suggestions.
