I have PeoplePutty, the Addon Pack and the Accessory Converter, Peopleputty is great for heads, and for doing the head textures, as well as doing the make-up and eyes, the addon pack adds quite a bit for accessories but they don't all work with the full body females, which is why I've been creating my own accessories and addons. As far as using one head on a different body, well myself I have no idea if it's even possible to do. I'm sure tho that if it is at all possible somebody here WILL figure out a way to do it. Will just have to keep watching the forums.
