Rather than going through the pain of starting the entire female soldier model from scratch, I found I was able to deform the male version to fit over the shape of an imported female MakeHuman model, with what I think are decent results.
Yes, I know parts of the texture are off a bit now, but I think I've just about got the shape of the body.
Hopefully Migel will have time to help out re-building the texture when he gets back from his trip sometime soon.
The white thing is the imported guide from MakeHuman, and the old male head is still in there - that will be replaced of course - and the skeleton hasn't been re-fitted for the female shape yet, but I think the hard part for the body shape is done.
