Ca'nt wait!

I know you said you were writing this script to transfer from V1, V2 - V3; and I suspect once you cross any base subsequent base transfer would be easier, but would it be possible to convince you to start with V3 to V4, or would the body part differences be a pain?  I would think you'd find a much greater reception V3 -V4, as a lot of work, that's about to be thrown away for V4, has gone into V3!
