Because Ever After High is fairy tales, and very rarely does Mythology fall under fairytales. It would also be very complicated and difficult to replicate Mythology, since (particularly in Greek and Roman), there's incest, backstabbing, illegimate children, angsty gods and complicated plot twists.

There are a few exceptions! Personally, I'm a huge fan of the headcanon that Cupid's going to follow the destiny of Eros in Cupid and Psyche.
