What was the reason for changing the line in the first place if I may ask? I interpret the line as Leia quitting because she is afraid of losing her son, only to realize that the only way to save her son and the galaxy is to embrace her Jedi training despite the fact that Ben might die in the process. If anything it would be cool to lean into this as a sort of character arc and imply that maybe throughout the movie she’s struggling with the choice to help save the galaxy and lose Ben or do nothing. This also explains why her corpse disappears only when Ben does. And, at the end of the day, they both still get a happy ending, as they’re reunited as ghosts thanks to Jonh.
