I am not sure if I understood what the problem is. Usually you can just copy the System Folder to any other volume the computer can mount at boot time and it works fine. Paths from aliases might get messed up, but can be fixed manually (for example aliases of application programmes you put in the Apple Menu).

Cloning of any pre-X-toric Mac OS is easily done by copying, except some varieties that want to work from a CD, only.
