If it wasn't clear already, yes Squid can use multiple resolvers BUT
they need to be recursive resolvers and every one of them needs to be
able to resolve *all* possible domains Squid will ask about.

You cannot have one of them being authoritative for local domain names
and another for public queries. DNS don't work like that.
