I'd like that too, but I don't see the other Amazons as having notable parts in a WW origin film. For the most part, they are simply Diana's background. The story is about her leaving them, and Diana's conflict with them is represented primarily by her relationship with her mother. There may be one or two lines to be said for an Artemis or a Phillipus, but I wouldn't spend a lot of time casting a name or a bombshell in those roles. That said, I would love to put Rosario Dawson in for Phillipus.
