Like, a Sailor Moon esque Elseworlds?
Diana could be sent Man's World by Hippolyta, and goes to high school with Steve Trevor and Etta Candy.
She could have a Amazon Scouts team to combat the forces if Ares. These could be:
Wonder Woman(Diana of Themyscira)
Wonder Girl(Cassie Sandsmark)
Shimtar(Artemis of Bana Migdhall)
They could have colorful costumes and fight the monsters that Ares sends against them. Ares could also have his own team of villain girls who are actually students at the high school.
Silver Swan(Valerie Beaudry)
Doctor Poison(Maru Yamaguchi)
There could romance and lame jokes and special poweruo weapons that are in magical girl anime. On top of that, it could easily be marketable to girls.
