Hair on female figures tends to block any minor misalignment at the upper neck/head seam due to different cross-sectional shapes, so a figure with shorter hair will probably be a little more trouble - but a little Taper can be used to tweak it for a specific viewing angle. Another point is that unfortunately, cr2's created in this manner cannot be shared because the new figure now contains the actual head geometry, rather using a pointer to the obj in the Geometries file. But I suspect a CR2 hacker smarter than I could find a workaround for that with a little text editing.
