It seems kind of unfair to hold some dated writing against Steve. Him getting captured is hardly a bad thing, because then it allows the female hero to rescue her love interest. And just update the origin so they don't fall in love instantly. Unlike some, I didn't have a problem with Azzarello writing Diana as seeing Steve's crash as a call to adventure, not true love. Start them as friends and allies, and develop a romance from there. Fairly easy, and a much better modernization than making Steve a middle aged dude who has nothing to do with her besides the convoluted scenario of having his mother share the same name as her.
Like it or not, human psychology (including the sexual spectrum) is pretty entrenched in Wonder Woman due to Marston. In Supergods, Morrison stated that post-Marston Diana has always seemed like a bland mix between the Virgin Mary and Mary Tyler Moore. While I don't think that's true in every case, he's not entirely wrong either. It's the unique combination of classical myth, girl hero adventure stories, and psychological and sexual themes that make WW what she is. She seems neutered without the last two components. It shouldn't be at the forefront of every story, or even most of them, but I think the ultimate female hero being in touch with her sexuality and it being portrayed as positive would be a good thing.
