I'm not a wing chun guy and i don't know if this conflicts with the whole centerline theory thing, but how about making the body able to twist? To further explain, trying to simulate a human torso by making it able to twist 90* left and right, but the further it turns away from natural position the tension and pull increases and it takes more effort to push it further? maybe use some sort of internal spring system. I don't know, i'm working on a scale model but for a specialized jong.
