Double bladed Rey edit

Hello guys. Today I will raise a question to you. Is it possible via edit to give Rey a double bladed lightsaber in some movie?
I think there is no place to it in TFA, and could exist in TLJ, but is improbable. Tros maybe the best place to it because of the time jump. We all know that Colin Trevorrow’s Duel of The Fates would feature a double bladed blue saber for Rey. That is the logical move because in TLJ the saber was split in two and Rey is an expert in staff combat. Hal 9000s edit of TROS feature a stable blade like Kylo’s and that make sense, it was cool. But it wasn’t enough for me. Even her new yellow saber by the end of the movie is confirmed to not be a double bladed one. Is it possible to edit her saber in TROS to be a doubled one? (Could be a similar one to dark Rey, or two saber’s that ‘glue’ in each other, Inquisitor style. Would be cool if there were two blades, one could be blue for the Skywalker crystal, and other q cyan blade… I don’t know. I’m just wondering. I know it would be a really difficult task to edit, but I wonder: it is possible at least to edit the yellow saber from the final scene of the movie, to be a double bladed one, Bastilla Shan style? Gimme your thoughts please.
