I have given up, hoping for a line that is in scale. For me, the scale should be the Alt mode since that is the disquise. Then, if the robot needs to be a certain size, the transformation should take care of that. I seem to be in the minority since Robot scale is what we seem to get. I have finally come to terms with the scale of the Alt modes because now all I have to do is place the larger vehicle closer to the camera and now they are in scale. As far as the Ratchet mod, you have a lot of work ahead of you but you are off to a great start!
