That's an interesting workaround. My zip code is also a Comcast service area so that part would be easy but the pain of going through Guided Setup twice on a Tivo HD is a huge deterrent. I might do it if I had some confidence the Tivo would be updated promptly but with my luck, I'd probably switch and two weeks would pass without anything happening. I have too many upcoming recordings that would be messed up. Would be interested to hear if someone else tried it.
