Hmm, why would you do that?. AD is a combination of various standard
services (kerberos, ldap, dns, etc) with some magical propietary glue. You
can try, but that probably won't end well. For example, when you add nodes
to AD, the AD server should automatically add them to the DNS zone, and
there are some special entries that manage the services, that are
automatically managed on AD server promotion/demotion.

If you already have an internal authoritative server, used for example for
Unix/Linux boxes, you're better off creating a different subdomain for AD.
If you use kerberos for example with that environment, this will allow to
setup external trust relationship between those domains. Keep in mind that
only one of the two can be authoritative for reverse resolution of each

If you want to have only one domain and you don't have any integrated
services like kerberos that depends on it, you'll probable better served
moving everything to AD and leaving pdns for public (Internet) services.
