That is awesome (and I personally also always err on the side of safety/privacy there), but I don't think this will help much. Anyone that can set your setup up can also just openvpn to a remote server, and redirect all DNS queries over that connection (which is quite easily doable, actually). Everyone that can't do this would still use SNI, so DNS-over-HTTPS wouldn't provide any security win for them.
