For anyone interested in the answer to the question I posed in the post just preceding this one, here are a few answers:
You can add drivers from multiple systems to the image and Windows will still do the detection of drivers as normal, it will simply have more drivers available to detect.
I've created an unattended install image that has the drivers for all my systems injected so I can now install on any one of my systems and all the drivers will already be installed after installation.
