How much extra clearance do you need for the handle bars so you do not have to loosen and turn the bars? Did you try swapping the bikes to see if the other bike's bars are shorter? If you could get by with shorter bars and brake/shifters have room to slide in a bit, use a pipe cutter to the bars equally on each side to make slightly shorter.
Likely 2" to 3" would be safe with as little movement the bikes have. The handle bar of the inside bike just touches the front cap. I may play with placement moving each bike out from center a bit more. Because of the location at the pin box, bounce is almost zero, movement is more a small wiggles, not bouncing like bumper hitches.
