Yes, writing an NSS plugin would have been the next resort.  It's
certainly easier than getting glibc and all other resolver libraries to
support ports other than 53.  But it's more difficult than the solution
that was actually adopted, namely, to make nm-dnsmasq listen at
127.0.1.1.

(BTW, I don't know if it has been mentioned earlier in this thread, but
one drawback of the adopted solution (i.e., making nm-dnsmasq listen at
another address than 127.0.0.1) is that it breaks name service on
machines that have no /etc/resolv.conf. In that case the resolver acts
as if "nameserver 127.0.0.1" were specified. Granted, Ubuntu Precise and
higher machines should *not* lack /etc/resolv.conf.)
