Yes, I agree with pretty much everything you're suggesting there. Except...

This image update circuitry cannot be in factory configuration image.

Why not? I'd question why you would not want the factory image to be able to update the boot flash with a new application image.

Consider the case where an application image update fails. This may be due to image corruption or a power failure during the update. When the unit attempts to boot to the application image next time, it fails and defaults back to, or remains at, the factory - assuming that's what you set it up to do. If, from that state, you're unable to accept a new application image, where does that leave your hardware?
