That solution works.

No cross references are resolved during loading...

Perhaps instrumenting your resource set's getEObject would be best.
Proxies are resolved lazily on first access and all such access will
call ResourceSet.getEObject. It delegates to ResourceSet.getResource
which, ultimately calls ResourceSetImpl.demanLoad the first time that
resource is needed. So perhaps that's the best place to intercept the
fact that a URI referring to a CDO resource needs to be redirected in
