We did something similar, but used the manual selection process instead.
remember, you can re-upload the original image under a seperate name and have it as a fallback if need be.
Also, you can test with a couple of phones first by putting them into a seperate device pool or resetting them indiviually.
Lastly, just a quick note, from testing we learned that the thumbnails that are shown under the phone preferences are downloaded from the cucm server - though the currently selected image is kept as a local copy.
