On a more critical note: separating a story (diegesis) from the telling (narrative structure) is like reducing animals to skeletons, disregarding the sinews, fascia, nerves, flesh, and fluids that make up an animal.
For example, describing Alain Robbe-Grillet's "La Jalousie" as a story about a man who suspects his lover of adultery is reductive to the point of atrocity. That particular novel tells the story using pioneering metafictive techniques and reducing it to its narrative types would yield very little insight.
