It depends on the context of the mod, as to what makes sense as a "path".
But in current Dominions terms, it seems that most of your list would be schools of magic, not magic paths. The difference of course being that a school describes what can be done with your magic, and the path is where you derive your energies. So paths necessarily must be something primal, such as elements, but I fear the most you can really hope for is recategorizing of what exists, it doesn't seem that there are many "previously unheard of" sources of magical energies. Sex magic is good, but perhaps not entirely appropriate, as Endo complained.
