Cloning the OS is totally possible. It is not required to disassemble and reassemble the OS. A comparision. You can copy the .exe from Adobe Photoshop, but you can't disassemble it easily. Got the point? Cloning the OS was done before with the older tablets. Booting from SD-Card, too. Flashing the OS from SD-Card could be possible, too, if the OS is booted from SD-Card, too (internal OS not in use).
