They haven't confirmed anything about who or how many costumes they're working on, so none of those concepts could end up in the final pack. The Captain America costume's the best since it's simple and the A being taped to the mask is a nice touch. I'm just glad the Wolverine costume isn't made of a wifebeater, jeans, sideburns, and somewhat spiky hair.
Sony also has the Spiderman movie license, Rolento, so that blows your Sony/DC theory into pieces.
