That would kind of remove the Poseidon and trident visuals and Ventura. Hyperboreans lived in a land of eternal spring paradise and worshiped Apollo. the place is described as 'long-lived, untouched by war, hard toil and the ravages of old age and disease.' (a lot like themyscira really...) Also, they already have a theocracy of 3 giants known as the Boreades, who were kings/priests and sons of Boreas.
I already know I'm gonna get the 'F**k off with that myth accuracy' treatment but, like its I feel like you can have the Hyperboreans and let Clea be her own thing.
