Certainly. dynamicsoft's product works this way.

Contact has the same meaning in REGISTER no matter where you send it. The
Contact header indicates the set of registered addresses.

Nothing is different if the registrar is not co-located with the proxy. The
registrar will store the registered addresses, presumably in some shared
storage that the proxies can access. When a call arrives at the proxy, the
proxy queries the shared storage, and finds out the registered addresses.
Same as if the proxy and registrar were colocated.
