It's good to start brainstorming now. The more time you have to think things through, the more time you have to catch those flaws in your planning.
If your heist/scheme goes well and you haven't otherwise made private, I say you should use it to request a rank up. It's the kind of initiative they like to see--though I know you can still get promoted without leading your own heist if you play a key part in someone else's. (That's how Steve P made private--when Dirk lead us on the big lapras heist, he had Steve P be the one to attack the lapras' keeper and secure him away so he couldn't interfere.)
