AFAICT, using Samba's internal DNS works fine with multple DC's. But perhaps I've missed something.

Well, you won't be able to "reprovision" without destroying your domain configuration and all the Kerberos trust relationships between the Windows clients and the DC. But I believe you can modify your samba config and change from using internal DNS to BIND. [I'm not sure about re-creation of all the DNS entries - that may be something you have to do by hand.]
But IMO internal DNS works fine [at least if you don't need to act as an auth dns zone for a zone outside of the dc's dns scope.]
Disable systemd.resolvd and it works fine. [Or use Louis' method - I'm pretty sure it works, but I had difficulty with it and found it easier to simply nuke systemd.resolvd.]
