Baring cosmic influences, I would expect so.

I think that any given system is the product of it's various components. 
  Change any of those components, and you change the product.

I see the list of components as being at least:

  · world file
  · portage config (/etc/portage)
     · USEs
     · accepted keywords
     · accepted licenses
  · portage files (/usr/portage)
     · this significantly influences the version of packages that get 
installed, which is quite important
  · kernel
     · version
     · config

Copying these things across should get you a quite similar system.  I 
suspect you would be down to how different packages are configured.

But the world file is only one of many parts that make up the system.

I didn't include distfiles because theoretically, you can re-download 
files.  However, I've run into cases where I wasn't able to download 
something and had to transfer (part of) distfiles too.

If you're going to the trouble to keep a system this similar, why not 
simply copy the system from one drive / machine to another?
