I think the new illustration works great and should be left alone.

We already see the lightsaber looks different and that Rey fixed it. It doesn’t need more explanation than that.

We see Kylo’s Wayfinder at the beginning of the movie and it leading him to Exegol. Rey hears Exegol and remembers reading it in Luke’s journal and it says you need a Wayfinder to get there. Easy.

Force healing is the issue. It randomly pops up out of nowhere in the film. Seeing the hint of it early on in the texts and then having Rey enforce that she learned it by reading the texts later on works wonderfully.

The ancient texts work better when they have knowledge of unknown force powers. Not being an encyclopedia of new items in Episode IX. Save that for Luke’s journal.
