I've dissected the update and found that the files are indeed signed. Someone with the right resources could certainly find a way to circumvent that as well as install a different OS. Then it would just be a matter of getting the system talking to the rest of the car.
The Windows Automotive debugger would definitely come in handy and it only costs around $7000. I work with WinDBG at the kernel level all day long. If someone wants to buy the tools and supply a donor vehicle or hardware I'd be happy to take a crack at it.
