If we could somehow do a wholesale saber replacement throughout and have her use Leia’s to replace Anakin’s which broke in TLJ, then Luke gives her his green one on Ach-To…that’d be an interesting experiment. But it might not work given how much dialogue is centered around “[Leia’s] brother’s saber.”
I agree. Should have been, but may not be able to just be implied. But maybe! But maybe not.
But maybe.
