Surmising Greek lore as a singular body of literature is a stretch in and of itself because the sources would at times vary between each region it came from (really, that's the case for a lot of religions). Could you point to a source you say inspires MLP?
If you'd like to style your path, belief, and practices with My Little Pony, that is entirely up to you. However, few others do (and none that I've heard of) and thus would not be able to relate using its terms. Given that there isn't much other context provided in your statements on what your beliefs and practices are, there's not much to go off of until you more clearly state your intentions (again reiterating the importance of relatable terminology).
