I think it would certainly be possible to end after Poe reacts to the now-last line “… a little girl he was supposed to take from Jakku to the Emperor.”

It may be news to them, and remains ambiguous about Palpatine’s plans. I’d imagine hearing that as consistent with what’s been established about trying to kill her.

(Even with the plot description quoted above, it still makes no sense why Palpatine decides at some point to kill adult Rey and just accept death. We’ve no choice but to alter that convoluted chronology with this edit. Now, Palpatine sensed her power as a threat and wants her dead. She reappears as a light-sider as an adult and still must die. Ben is redeemed and so he figures it’s worth trying to claim Rey as a vessel.)

EDIT: And as a missive, it helps a lot not to be additionally burdened by making sense out of Leia (and perhaps Luke) somehow knowing Rey was Palpatine’s granddaughter before TROS.
