It is the easy answer, yes. I was considering having Anakin use his kiber crystal inside his lightsaber as his focusing crystal and it basically being unimportant in the OT because Vader never has that lightsaber again. Obi-Wan loses his sometime and figures he’ll never get it back because that’d clearly be a trap.

Then in Draft OT they can go on a foolhardy and desperate mission to get Obi-Wan’s crystal. And handing down Anakin’s lightsaber is meaninful because in this trilogy the crystal works with any blood relative of the original Jedi it was attuned to.
