Actually, the Jag's theoretical swing axle radius is within contemporary standards - just over the track width. It will compensate about 45% for roll camber change. Probably a good compromise. If you have 2 degrees roll with a static camber of -3/4 degrees (stock setting), you'll end up with +1/2 degree at maximum (street) G force. A shorter swing axle radius will make the rear end very sensitive to chassis height change due to power squat or brake rise.
