I do research in this topic. While word level features are readily available and provide some interesting insights, I'm more interested in syntactic phenomena (e.g., recurring phrases). But in the case of The Simarillion the "reading difficulty" could be beyond even that; I suspect it might be because it doesn't build up suspense the way the traditional narrative of a novel does. Unfortunately, that might be hard to capture in a programmable test.
