If you need any "special" DNS features, I don't see why they should be
implemented on the Gateway. They can equally easy more and safely
implemented on the Workstation(s) were needed.

Things I tested: DNSSEC over Tor, DNSCrypt by OpenDNS, httpsdnsd by
JonDos. [1]

There is no reason why ttdnsd or dns cache wouldn't work on the
Workstation/AppVM.

I see. Not sure, if possible, but could you remove all such
unnecessary applications? Maybe make it very clear as desktop
background or automatically opening text file?

Whonix as a optional configuration "Hide the fact that you are using
Tor/Whonix". [2] Not sure if the TorVM use can be easily hidden. Users
would have to download the templates over Tor.
