You might be able to "borrow" the look and feel by getting the cab installers, saving you a lot of headache. Chances are that these are installed during the first boot and the cabs live in the ROM so they can be reinstalled on the next hard reset. They aren't really in the image, so to speak. You just need to find out where they are.
A lot of people don't like these and they forcably terminate the installers on the first boot.
