Usually, in applying a pose from one character to a totally different one, the biggest snafu is with the hands. For example, I find most Posette poses (and there are lots available) work pretty well with V3 except that the hands get totally fouled. I therefore keep a little collection of basic V3 hands (downloadable from my home page should you be interested) for correcting the hands after applying a non-V3 pose. Why the hands should be such a problem area I don't really understand.
