Let's hope he does, there's always room for improvement anyway. A good costume to use would be the one from Superman: Earth One
-it has great-looking boots.
BTW, I came across an article about the concept of casting a black Lois Lane, and how it would fare: Chromatic Campaign, anyone?: The Case For Rashida Jones To Play Lois Lane
I don't think he really has any other choice than to be traditionalist or extremely close to traditionalist. They fan backlash would be unprecedented and the problem with that is that everyone is a fan of Superman. Whether they are a "big" fan or not, Superman is so much of an icon that messing with the iconism of him would be messing with like everyone's childhood.
Exactly what I've been saying about the casting of peoples of color.
