Many people think Jaimie Alexander would make a great big-screen Wonder Woman, and she has actually spoken about the prospect on a couple of previous occasions. Alexander feels that - done right - the character could work as a great role model for young women, but done wrong:
"They tried to reboot Wonder Woman, which was a huge embarrassment if you ask me. Adrianne Palicki’s great, but you can’t take someone – no matter how talented – and put them in a trashy costume, then say they’re supposed to be a positive role model for women. I don’t think she got into it thinking that’s what they’re going to do, and I think she played her hand as well as she could, but that project was just not the way to go.
I’ve actually been approached a couple of times about it. I think right now, my loyalty is to Marvel. But yes, I’d love to play more characters like Sif: keep the young girls of the world safe from slutty costumes and poorly written scripts!"
So, it's a possibility! And if Alexander ever did feel like strapping on the gauntlets, she could look a lot worse as Diana than she does in this manip from the
