Possibly feasible with local netfilter/iptables rules or maybe userland proxy/rerouter. set /etc/resolv.conf to localhost:53, have that forward to 8.8.8.8:1053 or whatever, but without encryption it could be detected I'm guess with deep packet filtering (hopefully beyond the thoroughput constraints of eyeball ISPs)
A good way of bypassing this would be to simply have Google run their DNS server in a port other than 53. But I don't believe you can set a different port in /etc/resolv.conf
