adding scale to dpAutoRig

Hey guys, I've been using dpAutoRig (http://nilouco.blogspot.com/2011/10/dpautorigsystem-v-20.html) for a personal project. It works great except that I recently discovered a need to scale up the character and unfortunately this system does not support that. I know it's a long shot, but has anyone had any success adding this functionality to this particular rig? Thanks!
