It'd be lame if he had CoC. But at this point less qualified individuals have gotten it.
The answer to why Law doesn't have it is Luffy. It allows Luffy to stand out. Awakened df, D and CoC is too much for anyone not named Luffy, maybe Teach.
Luckily for Law Oda made his df so broken that he doesn't need anything else. Maybe that's why he gave Law the ope knowing he wasn't getting conqueror's but still had to be among the top of his generation.
