[DC] What would happen if Batman, Superman, and Wonder Woman started their careers as teenagers?

I was going to ask about all the Justice League founders, but I figured I'd stick with the big three for now.

Batman would be less effective.  He'd basically be a robin without a Batman to  train him.  He'd probably have to rely on stealth more since he'd be physically weaker and probably not have as good equipment.   

Superman would still have all his powers, so the only real difference would be his mindset.   He always had a good sense of right and wrong,  but he'd probably make more mistakes and some rash decisions when he first starts out.  He'd struggle even more against the manipulations of people like Lex.   

Wonder Woman would also still have all her powers, but leaving Themyscira at an earlier age might make it a little more difficult for her to adjust to the Earth.  She might at first have more trouble leaving behind some of the Amazons more violent tendencies.
