I believe this is somewhat incorrect
Let me just clear up some confusion before I debate why this is incorrect
Roll Couple - the measure of the distance between the Roll Center and the Center of Gravity
Roll Center - The roll center of a vehicle is the notional point at which the cornering forces in the suspension are reacted to the vehicle body
A higher roll center is what causes jacking force, NOT a lower roll center or longer roll couple. I think you may be confusing several of the terms and definitions
Also, do you have the measurments of the front/rear roll couple?? I have a feeling the front is actually shorter than you think since the CG is slightly above instant center (a little below 3/4 way up the tire height from the ground) and the Roll Center is a little below or at 1/2 up the tire. I could be wrong, but here is a diagram from our strut based front suspension hence why I question
