You're talking about using the original V4.2 skin texture as a template to line-up your created version?  Sure.  Just look in your V4 textures folder.  If you are also using the seam guide as reference, open both the seam guide and texture files in Photoshop, select your texture, hold down shift and drag & drop your texture as a new layer over your guide.  By doing this, the texture and seam guide will line-up and match.  Similarly bring in your new texture for further work.
