For a public DNS64 service you also need a public NAT64. I suppose anyone willing to run a Tor exit node might be also willing to run such a service but it would be a traffic source anonymiser and likely would be abused.
That said I could see it as a commercial service where only certain sets of IPv6 clients get to use the service with a strict mapping to IPv4 source addresses, logging etc. A ISP which had already set this up for themselves and had enough IPv4 addresses could offer this to IPv6 only ISP's as a service they could buy. Similarly a consortium of ISPs could set this up for their members possibly pooling IPv4 addresses from the members. Someone like HE might like to run such a service to further promote IPv6. This is something transit providers might get into. IPv6 to IPv4 Translation services for IPv6 only clients. The same arguements also work for DS-Lite.
