Thorgrim... two ways of doing it. make a GS hood right over it or cut the top/back of the head off with a dremmel tool or saw and then GS the hood around the face and what is left. But it sounds like a pretty good idea.
GSing a hood should be easy.
I GSed a converted doomseeker and a few tips:
1. keep your sculpting tools clean with some water and a cloth. A little petroleum jelly will keep the GS from sticking to the tools and make the sculpt smooth easier.
2. Have a desk lamp near by to spead up the drying process for the GS.
3. only mix a little GS at a time. It doesn't take much.
Finally I think your leather idea sounds good. have you thought of trying to dip your army in minwax? Seems 'dipping' is the current craze and it makes a model look pretty good to.
