The best versions are those that whole heartedly embraces the greek mythology thing. Be it Perez, the animated movie or the recent Azarello run.
Imho, the greek armor concept is the only thing that makes sense from a "world building" perspective, especially for a movie. Now, one can argue that WW in MOS 2 is an already established figure who has spent a lot of time in "man's world" an thus adapted her costume. However, if she's fresh of the island so to speak I say go with a greek armor influenced design.
I would cut a leg off to see a Wonder Woman film based on Azzarello's run directed by Del Toro, so in a sense I agree with you. Yet, her costume in the nu52 have nothing to do with ancient greek mithology. You could argue that the armor she uses to travel to Hell is, yet it's not her default one. It was even rejected for that role and then reused in the that particular story arc.
But I'm not saying I don't think a Wonder Woman costume shouldn't resemble an hoplite/roman armor or something in those lines. What I'm saying is that most fan made designs I see with that idea are mediocre. And mediocre just won't do. First and foremost it has to look good. Everything else is secundary.
