If it can be built, someone else can tear it apart and rebuild it.
The issue is that the Kindle now checks to see if it is an official Kindle update before applying it and faking the signatures is to all practical purposes impossible. It won't be quite as easy as before where you could just drop any update or patch onto the Kindle drive and then let it run.
That said, there is always the possibility of a flaw in the update process which allows a custom update to be crafted but there are no guarantees. It may end up that you need to connect to the debugging port on the side of the Kindle 3 which means needing the adapter hardware.
