let me ask the question, why you would need to copy to another authoring instance. In "traditional" AEM setups that's never the case. So can you elaborate on your requirements?
And technically replication is fine (the author does not care, what role the target system has), but replication has some edge-cases, which doesn't it make suitable for all kinds of "AEM-to-AEM" content transfers. For example, ACLs are not transfered.
