Hmmm perhaps; possibly something resembling this only with the breastplate being gold (like the smaller breastplate picture) and the leather straps green with gold markings (much like Herc's comicbook sash)?
Obviously, the get up that Herc sports in the comics wouldnt look to great in live action. I totally get what you're saying but my main concern is that if you dont go with the all over armor approach that they've already applied to Thor, you run the risk of Hercules looking like DC's version of the character:-
