I agree that luthor is a great villain for Bruce Wayne. I am not sure about Luthor as a villain for Batman specifically.
Agreed. The reason behind Lex Luthor being a rival to Superman is because he hates Superman for taking the limelight away from him when he feels that he should be the one the world looks up to for his great intelligence. He generally wants to help people, but he wants to be the one that does it alone so he gets all of the attention (and the power the positive attention brings him). Notice that in pretty much all other universes where Superman isn't present (or is evil), Luthor's a good guy.
I doubt he'd be an enemy to Batman, because Batman isn't a rival. He could be an enemy to Wayne because Wayne could surpass him in being a world-aiding philanthropist.
