Hey Guys,
I went ahead with the wrapping paper because I didn't actually have time to wait for anything to come in from e-bay, though if I do another one of these I'll make sure to get it.
It works fantastically, I use double sticky tape that had a mildly conductive adhesive and doubled over all the edges of the wrapping paper so it all contacted the same side. I finished the guitar yesterday and will be posting photos soon. It is totally silent and sounds AMAZING!
Thanks so much for your support!
