I too think that the WWE wouldn't copy something from TNA. I have to agree with WWEFreak and say that if they tried to do something like this WWE should use their move sets instead of the nationality. I would have 6 teams and my teams would consist of 4 members and the teams would be as follows:
High Flying Team: Jeff Hardy, Rey Mysterio, John Morrison, and Evan Bourne
Hardcore Team: Edge, Tommy Dreamer, Kane, and William Regal
Submission Team: Chris Jericho, CM Punk, Finlay, and Charlie Haas
Wrestling Team: John Cena, Jack Swagger, Ted DiBiase, and Shelton Benjamin
Brawling Team: Batista, Mark Henry, Vladimir Kozlov, and Jamie Noble
Giants Team: Big Show, The Great Khali, Ezekiel Jackson, and Mike Knox
I would have the teams feud from the end of SummerSlam all the way up until Survivor Series. During this time there would be a series of singles, triple threat, fatal four-way, and tag matches between the teams. Then, at Survivor Series, there would be a tournament to see which team is the most dominant. The teams would be paired up in 4 on 4, elimination matches that were chosen randomly. I would have the Teams face off like this:
Submission Team (Chris Jericho, CM Punk, Finlay, and Charlie Haas) vs Brawling Team (Batista, Mark Henry, Vladimir Kozlov, and Jamie Noble)
Winning Team: Brawling Team - The end of the match would come when Chris Jericho has the Walls of Jericho locked on William Regal then, right before Regal is about to tap, Batista hits the Spear on Jericho for the 3 count.
Hardcore Team (Edge, Tommy Dreamer, Kane, and William Regal) vs Wrestling Team (John Cena, Jack Swagger, Ted DiBiase, and Shelton Benjamin)
Winning Team: Wrestling Team - The finish of this match would come when Edge hits the Spear on Ted DiBiase sending them both to the outside of the ring. While William Regal is being double teamed on the outside by Shelton Benjamin and Jack Swagger, Kane goes flying off the top ring post onto all three men fighting on the outside. This left Dreamer in the ring to get FU'd by Cena for the 3 count.
High Flying Team (Jeff Hardy, Rey Mysterio, John Morrison, and Evan Bourne) vs Giants Team (Big Show, The Great Khali, Ezekiel Jackson, and Mike Knox)
Winning Team: High Flying Team - The finish to the match would come when the ref gets knocked down after a clothesline by Mike Knox. All 4 members of the High Flying Team grab a weapon (Hardy with a chair, Mysterio with the ring bell, Morrison with a Kendo Stick, and Bourne with a Steel Pipe) and they beat down the Giants Team. The ref then starts to come to his senses and everyone hits their finisher on Ezekiel Jackson who was left in the ring by his partners. Evan Bourne would get the 3 after his Shooting Star Press.
The Submission Team vs The Brawling Team would be the opener for the show. The Hardcore Team vs The Wrestling Team would be the third or fourth card on the match. The High Flying Team vs The Giants Team would be like a upper mid-card main event during the show. This would leave some time between the matches to have title matches on the card still. The final match between The Brawling Team, The Wrestling Team, and The High Flying Team in a three-way tag team elimination match would end up being the Main Event for the show.
Brawling Team (Batista, Mark Henry, Vladimir Kozlov, and Jamie Noble) vs Wrestling Team (John Cena, Jack Swagger, Ted DiBiase, and Shelton Benjamin) vs High Flying Team (Jeff Hardy, Rey Mysterio, John Morrison, and Evan Bourne)
The Team that ends up winning the match is the Wrestling Team - The Eliminations would go something like this:
First person eliminated: Jamie Noble after Mysterio hits the 619 in the first few minutes of the match.
Second person eliminated: Rey Mysterio after Mark Henry catches a flying cross body and reverses it into the Worlds Strongest Slam.
Third person eliminated: Ted DiBiase after Batsita hits the spinebuster followed by the Spear.
Fourth person eliminated: Mark Henry after a Swanton Bomb by Jeff Hardy and a Shooting Star Press by Evan Bourne who gets the 3 count.
Fifth person eliminated: Evan Bourne after a Gutwrench Powerbomb from Jack Swagger.
Sixth person eliminated: John Morrison after an FU from John Cena.
Seventh person eliminated: Shelton Benjamin after a running headbutt from Kozlov.
Eighth person eliminated: Vladimir Kozlov after an accidental spear by Batista that was aimed at Jeff Hardy but, Jeff Hardy moved out of the way and Kozlov got the spear, Jeff Hardy covered Kozlov after this.
Ninth person eliminated: Jeff Hardy after a Spear from Batista. This would also eliminate the High Flying Team from the match.
Tenth person eliminated Batista after Jack Swagger went for the Gutwrench Powerbomb that was reversed into a Spinebuster then, John Cena enters the ring after a blind tag by Jack Swagger and hits the FU on Batista. This would end up giving the Wrestling Team the win.
