Quidditch Croquet Rules!

On Tuesday I'm going down to Florida for LeakyCon 2011, and I am PSYCHED . . . to speak at Lit Day, to see the Wizarding World theme park for the first time, to party with Harry Potter fans, and because my hotel has a croquet court! (For the reason I'm obsessed with croquet, hit the "Frog" label on the right.) This obviously requires a game of Quidditch Croquet, which in turn requires the establishment of rules for Quidditch Croquet; and I propose the following for discussion/comment:
  1. Play shall generally proceed as in a standard croquet game, with the wickets in a figure-eight configuration, and in order of the colors on the post; but with the following exceptions:
  2. The black ball shall be the Bludger, and the yellow ball shall be the Snitch.
  3. Neither the Bludger nor the Snitch can play until all other balls have passed through the opening two wickets.
  4. -- The Snitch shall go first, and the Bludger second.  
  5. -- They should both start at the opposite post from the rest of the players. 
  6. The Bludger does not have to follow the standard course and try to go through wickets, but rather should spend its time trying to knock all the other balls (besides the Snitch) as far off course as possible.
  7. -- If the Bludger touches another ball (a roquet), it gets only one additional hit, instead of the standard two.
  8. ---- If necessary, an additional limitation can be imposed on the Bludger, that the player controlling it must play one-handed and/or with his/her less dominant hand.)
  9. -- If another ball (besides the Snitch) touches the Bludger, it gets three additional hits, instead of the standard two.  
  10. The Snitch also does not have to follow the standard course and try to go through wickets, but rather should travel consistently up and down the midline of the course, from post to post through the center wicket. 
  11. The Snitch does not want to strike or be struck by the other balls.
  12. -- If another ball (besides the Bludger) touches the Snitch, it gets four additional hits, instead of the standard two. 
  13. -- The Bludger is not allowed to hit the Snitch, and if it does, its turn is over and it misses its next turn.
  14. The game concludes when a player successfully completes the course, passing through all nine wickets and touching both posts (the opening post twice, at the beginning and end); 
  15. -- OR when the Bludger has knocked into all the active balls (besides the Snitch) twice (a scorecard may be useful here) and reached the closing post before anyone else; 
  16. -- OR when the Snitch has successfully completed thirteen post-to-post-through-the-center-wicket crossings of the court, including at least three where it was not struck by any other ball (ditto on the scorecard), and reached the closing post before anyone else. 
This allows the Bludger and Snitch to behave as they do in Quidditch, but gives all players an incentive to win. (I chose thirteen post-to-post perambulations for the Snitch because it would take a long time to reach,  I hope, and thirteen is a good wizarding number.)

Thoughts? Suggestions? And if you're going to LeakyCon -- who's in?
