I suggested earlier that Obi-Wan not fight with Vader at all and get left behind on the Death Star still pulling levers. Or he could fight Vader after being left behind, give up, and go back to pulling levers.
In the middle of the shot where the Falcon is reversing out of the docking bay, Obi Wan could unknowingly turn the tractor beam on and off again, causing the Falcon to be pulled back in partially before finally escaping.
