GCM with version 7.2 - Support for a "hierarchy" of SitePublisher sites

System

Using Teamsite 7.2 and the "Globalized Content Management" module that is now available out-of-the-box, is it possible to setup a "full tree hierarchy" of sites / site families such that one site inherits from the other in a tree-like structure, or do ALL locale-specific sites HAVE to have one single/common site master ?

Basically, is it possible for a child site to inherit from one master site, and then have that particular child site serve as the "master" for further inherited child sites ?

The scenario is as follows :

1. I want to setup a Master Corporate Site for US-EN. This will be my master-locale at the "top of the tree".
2. From that master site, I want to derive a child / locale-specific site for CA-EN. This is my second layer in the tree.
3. Now, using the CA-EN site as the "base", I want to derive the "next child site" for CA-FR (this is my third layer in the three), in other words, for the CA-FR site, I'd like the CA-EN site to serve as the master, not the US-EN site.

Is there a way to do this using GCM ?

Many other CMS packages that support multi-site, multi-locale, would allow for such "nested" / "tree-based" site inheritance relationships, allowing for any site to be extended off any other site, thus creating a full tree of locale hierarchies in a site relationship structure.

Does GCM support this ? If not, are there ways to workaround this, such that the locale relationships can be established as desired for content / site inheritance and dependency management ?
