I’d be okay with removing the confession thing as long as it’s reference underneath the sand can be handled in a way that is not jarring. Cutting abruptly to Poe leading the way with the flashlight is.
I may play with that a bit one of these days and see. Initial thought is remove all references of it and do away with the Poe and Finn bickering before they “execution” … basically tightening that scene up would be easy.
