No, but it may draw more attention to the characters. Continuity will continue in it's current iteration from the books still being sold by DC. Plus, indy publishers would have to begin their own continuity because they'd only have free-copyright to the first appearance books. All the stuff that developed along the way would still be under DC's protection (Luthor is what, ten years out? A Superman story wouldn't even be able to use him initially). It'll be the other weird stuff that I never thought of for these characters that intrigues me. It will be BOTH good and bad. I wish they were public domain right now. The current world stage is similar to that which spawned these guys.
