You most likely will not find a solution to your problem here. What you are doing, and what you are looking to do, is not supported. We just got lucky that Windows is not locked down, and have access to modify these files. So, unless someone has done this before, as was the case with me and with your original post, you're on your own to find a solution.
If I have some time to poke around, I will look for you, but don't get your hopes up.
Also, I have no experience with UCCX 8 yet, but I am 99% sure my original solution will not be available in 8. But I could be wrong.
