I don’t think you need to replace it with anything because it serves no purpose once you replace “Palpatine lives” with “Kylo found a thing” in the crawl.

I also really just don’t like the sequence as it currently exists in the film (which is unfixable without the deleted footage), and I feel it contributes immensely to the hectic feeling of the first act. Jumping to too many locations right off the rip is just so whiplash-y. Cutting one of those locations out would be a huge benefit IMO.
