I have other thoughts on the other flashbacks to the temple massacre and that event in general that I can share later. I do think you could potentially reuse shots from the various flashbacks to extend them and add more dialogue if needed, but I think a part of it is just adjusting word choices to get that idea across better in the same amount of time. Just depends on how detailed you want to be versus how minimally you want to change the existing dialogue.
This is definitely true. We could potentially show Luke looking at the burning temple again after where the third version of the flashback previously ends. Originally, that is only shown the first go around.
