This isn't possible. The internal DNS naturally requires to be on the
same host, of course. And BIND9_DLZ as backend also requires to live on
the same host, because it uses modules of Samba and access the LDB files
of the DC.

But why not running the internal DNS or BIND on the DC, authoritative
for the AD DNS domain(s), and configuring a forwarder on your external
BIND servers:

zone "samdom.example.com" {
         type forward;
         forwarders {; };

Then all users still use the current external DNS servers (the ones not
on the DC), but are able to resolve AD DNS requests.
