I'd look at using an air brush. You can use a light layer of silver paint to create the shimmer effect of the statue and, if you use a body suit, you'll only need to do hands, head and face. It will still take a little bit of time to get off afterwards though.
The only other option I can think of is a morph suit. You could cut out the face and then only use the make-up on that area. It would also be easy to add to the costume by layering.
