About the only way you'll get one to look like the other is to do it in a modelling application. The base mesh has been sufficiently modifed enough in vertice placement that the two figures do not look alike pretty much no matter what you do using the standard morph packs. With the sculpting set, however, you could likely achieve a pretty fair comparison. I happen to like s3 more, and she does take the v3 morphs.

thou and I, my friend, can, in the most flunkey world, make, each of us, one non-flunkey, one hero, if we like: that will be two heroes to begin with. (Carlyle)
