I like that sequence of events, but I feel like cutting the Boushh/Chewbacca scene makes the Lapti Nek bit feel like a non sequitur that only exists as foreshadowing, as opposed to a lead-in to the Boushh scene that also functions as foreshadowing. Plus, including the Boushh scene gives Threepio something to do immediately after his capture, which gives more connective tissue between that and Leia freeing Han than just using Lapti Nek, where Threepio is just a bystander who doesn’t do anything.
