Here is Superman vs. Power Armor Lex. Product number 6862 in the DC Superheroes line.
This LDD file doesn't include Lex Luthor, Superman, or Wonder Woman. Also, I don't know how to get the effect the blaster hose has where the outside is transparent but there's light green inside. And I'm not entirely sure about the shades of gray because the set has two different grays but Lego Digital Designer has three different shades of gray. But otherwise all the details are correct.
