I wasn't hopeful, because I had a good dig around. Ideally, I'd like to be able to define a few key points, and then have the mesh project as closely as possible whilst still retaining some of the original volume.
I'll look into link you provided. Might lead somewhere. Thank you for that.
EDIT::
Yup, that link looks like exactly the thing.
Shame it doesn't exist in H. I can't justify buying more software, but I'll certainly test it out with their trial.
