I think this should work but haven’t tried it. Set your scale factor as a variable. Eg. Desired root scale is 1.2 scaleFactor = 0.2. Then scale root bone by 1+scaleFactor. Then loop through child bones and scale by 1- scaleFactor. I think this should keep a relative scale, However I have had a drink or 2 tonight.
