I would really like it if we could somehow have Palpy yell something like, “Skywalker is dead!” Luke’s death made basically no impact on this film so anything to remind us of him would be very much welcome in my opinion.
Edit:
Just watched the clip, using only a portion of the message works surprisingly well, the only big issue is that it seems like removing “somehow Palpatine returned” makes Poe’s next line “He’s been planning his revenge for years” seem very abrupt, it makes it a little too obvious he’s already in the middle of a speech.
Poe’s later line of “so he’s been out there all this time pulling the strings” might work to fill that void before he says he’s been planning his revenge
