I doubt your idea is possible. Realistically, the trip downtown on the train takes about an hour, but this doesn't include the time to deplane and walk to the El station underneath O'hare. If you arrive at the gate at 9:30, you probably won't get downtown until 10:45 or 11:00. At that point, it would almost be time to turn around and head back to the airport for a 1:29 departure. Security lines aren't that bad at O'hare, but in the afternoon it could take you 20 minutes to pass through.
