"What other elements of greco-egyptian mythology are there even?" there are actually quiet a few. Sorry but this is going to be kind of a long answer.

First there's the three sphinx monsters, Heircosphinx (hawk-headed sphinx), Criosphinx (ram-headed sphinx) and Androsphinx (man-headed sphinx).

I know of at least one other Greco-Egyptian god besides Serapis. Harpocrates the god of silence, son of Serapis and Isis. His image is based on Horus the child who has a finger to his lips signifying innocence, the greeks misinterpreted that to mean "shush" and made him a god of silence.

Then there's fusions of Greek and Egyptian gods like Hermanubis (hermes anubis), Hermes Trismegistus (Thoth and Hermes) and Osiris-Diyonysus.

There's also egyptian characters from Greek mythology. Like Busiris, a son of Posiedon and king of egypt, who sacreficed foriegners to the gods at an alter every year because an oracle told him to. This ended when Heracles visited egypt, he was arrested and brought to the altar but Heracles broke his chains and killed Busiris. Then there are the Danaides the 50 egyptian princesses who were forced into arriaged marriage, they each killed their grooms before they could be wed.

As for how to go higher than Serapis I don't know. Do you think any of these elements would make for a good short story?
