I much prefer your version jonh. It’s much more subtle and seamless like sade1212 said. Judging from this teaser it looks like a cool fan project, but not something that would fit inside the movie, much like SC 38 Reimagined.
Kylos saber is like that to signify the rage inside of him.
Kylo’s saber was supposed to mirror his unstable nature, being torn between the light & dark sides. Rey struggles with a similar inner conflict in TRoS, so it makes sense for her blade to mirror this aswell. It also plays into the connection between Rey and Kylo, it foreshadows Ben taking on the saber, it fits with the damage inflicted in TLJ. It’s honestly mind-boggling they didn’t think to do it in the original cut.
