I don't think it's really worth a functional mod on its own, given the mod limitations (1 mod active per playthrough).
As part of a bigger mod that does other cool things, then yes it can. I'm planning on working a version of this into my Unfair Difficulty Mod soon after I get the Summons straightened out. When I do (and when I get functional Skillbooks to attach to it) I'll share the relevant portions so that someone else could use the functional skillbook in their mod.
