You can not *directly* connect to other upstream UDP DNS servers through
Tor. This is because Tor does not support UDP.
However, TCP DNS over Tor can work.
I successfully used DNSCrypt by OpenDNS and httpsdnsd by JonDos over
Tor. Although I documented it for Whonix, it should be possible without
Whonix over Tor as well:
(Note: Whonix specific!)

You can also have a look at ttdnsd:

Alternatively you can connect to DNS servers if you tunnel UDP over Tor.

If I understand correctly, this would be like "emule regular public
network and high id over Tor", i.e. open a server port at an exit node
and let it forward through Tor to your Tor client. Tor does not have
such a feature. It needs sender and recipient to be aware of using Tor,
can only be done with hidden services.
