Just keep the beer out at room temperature, and it might work out just fine. I've done successful diacetyl rests after kegging, so I do not see why it could not happen in bottle conditioned beer. As Yooper said, though, it may take a while. You have more than a couple weeks to go for carbonation, though, so the diacetyl may be gone by then.
Beer is good for anything from hot dogs to heartache.
