Ultimate Combo

Why not just combine every (non-judged) sport there is into one? Among all of the combo-sports ideas we have seen, this is the ultimate. Picture this:

The playing field:

Huge, perhaps three of four acres to accomodate multiple surface types. Mostly consisting of lawn, but with patches (hazards?) of: swimming pools, ice surfaces, hardwood, cement, dirt track, etc. An auto racing surface is interleaved throughout the field.

Players:

All manner of players, with several representing each discipline and occupying the field approriate to the sport they are suited for. Some on horseback. Some in race cars. Some wearing skates, others carrying raquets, whether tennis, badminton, or other. All should be wearing padding somewhere between what a baseball player and an American Football player wears.

Equipment:

One ball, leather, the precise average in size, weight and shape of each representative sport. Sports in which there is no "ball" (such as the various racing sports) do not contribute to this part of the game. The hockey puck will be considered here, along with the LaCross ball, the baseball, golf ball and polo ball, and every other ball.

Goals:

On each playing surface, a goal recalling the goal of its associated sport, but suited for the Ultimate Combo Ball. Also, end zones at the ends of the field like in rugby or American football. Score one point per goal scored, regardless of type of goal.

Rules:

When a player representing any given sport gains possession of the ball, the rules for that sport are immediately adapted, and the ball is moved to the nearest location that would be appropriate for that sport. The defensive team may involve three players in the ensuing play representing any of the other sports, and if one of those players gains possession according to the rules of the current sport, rule reverts to the rules of that player's sport, and the play continues with his team on offense. For a sport with no ball (such as racing) a slight advantage is given to the player intercepting the ball, and play continues in that player's sport.

For a sport with no offense or defense (such as golf or racing), play continues under those rules until a conclusion (one racer winning, the golfer reaching the hole in par, etc.). Possession is given to the team winning a race, or in the case of golf, if the player doesn't par the hole, then a scramble for possession (like a fumble in football) after the failed par attempt will determine the next offense and the next sport. Other rules can govern sport-switching, like perhaps the team on offense in a limited way can elect to switch by transferring possession of the ball from a hockey player to a shot-putter, for instance.

I don't know of any way to incorporate judged sports (such as gymnastics, figure skating and boxing) practically, but perhaps we could even do that.
