I think it's more complicated, different takes on the same formula, I can see at least 2 characters in each character.
Batgirl Twilight-nanners and Pinkie
Green Lantern 1/4 Rarity and 3/4 Fluttershy Environmentalists
Supergirl is Rainbow Dash x2
Wonder Woman is AJ and leadership Twilight
Zatanna is Rarity and... okay she's all Rarity
and Bumblebee, is Flutter"shy"
