I wouldn't recommend that. I think you underestimate the ammount of debugging that a quest requires the instant it hits the open market - no matter how thoroughly you check it for glitches, someone always finds a way to walk diagonally through the bar of the crane game, then someone else cries "hacker!", etc.
In any case, have it uploaded and locked so in case of emergency (ie, the server's eminent shutdown or takeover) you can upload the level with the link and Poof.
