Adding internal ip of machine hosting Aegir as separate server

I currently have Aegir set up on a single server. The server is set up with the external IP and one of the DNS entries that points there. The Aegir hostmaster platform is served on this server and while it is the only web (Apache) server there are several (external) db servers set up.

What I would like to do is host another Aegir managed platform/site on the internal ip address of this server (only). I was wondering if I could set it up as a 'new' server with an internal IP and DNS. I am assuming Aegir would see this as a 'remote' since it would be defined as different from where hostmaster runs.

What I am concerned about is how it would work, especially with Apache. I would expect to host all the sites with one Apache process bound to both IPs.

Would this work?
