Oh, I know what you mean: kinda like Captain D'Val's adventure in book 4 in which you see the same events but from the point of view of a secondary character. Of course, with what you suggest, it would need to be a bigger, longer adventure.
Who knows if JD won't try this out with one of the 2 remaining books of the series. After all, he said that they will both have 500 sections, so having one of these two books divided into a two-parts, 250-sections story could work.
