Newsflash: You can polish and refine an idea as much as you want. SE will never use your exact idea. You've given them a base to work with and that is all they will take. Your general idea, probably with a few vague details have already been passed on to the dev team to concider. They will take it from there and build an idea based on yours, but not mimicing it 100%. Refining it anymore will do absolutely nothing. Making other large breakthroughs related to it are more likely to get recognition.
Everyone needs to stop thinking that just when a mod replies saying "I'll pass it on to the dev team" that the dev team will use everything, every refined detail in the idea. If they decide to use it they will take the general idea, maybe some vague points from the idea, and then make it their own.
