I don't see why this would not be possible to setup. Where do you see the issue here? Remember that when setting up replication from backup files, you instruct the replication job to look for backups in the specific repositories. So, you just point your replication job to the location where Backup Copy job puts them (just remember to schedule auto-import of those backup files into D&R backup server's repository).
Let's not hijack this thread any further though, since discussion becomes totally unrelated to the original topic
feel free to create a new topic instead!
