It shouldn't matter if the person is dead or not, there is a shinigami after all
I ressurect all the time, why can't they?
I agree, it makes sense. Plus, we are jumping ahead with the manga. Others may not keep up with the manga, and may only watch the anime.
How about changing up the premise of the idea a little: The event would be called,"The Gauntlet-AKA 10 Doors".
You believe that you have found the Akatsuki Lair. There is only one problem though, there are 3 doors/openings in front of you. Do you choose Door A, Door B, or Door C (I'm using letters, for those that like to use hot keys). Behind two of the doors is a member of the Akatsuki, he's covering two of the doors, by using one clone. One of the three doors has nothing behind it. If you chose the right door you go on to the next set of doors. Each set of doors brings about a new member of the Akatsuki, waiting behind two of the doors. It is the classic and deadly game of Russian Roulette.
Now since the event is called the Gauntlet-AKA 10 Doors, there will be 10 members/associates of the Akatsuki that you will possibly have to fight(in no particular order):
a. Deidara
b. Itachi
c. Kisame
d. Tobi
e. Zetsu
f. Hidan
g. Kakuzu
h. Sasori
i. Yura
j. Clone of yourself
By being able to finish off these enemies, you will get certain things: By beating Kisame a water scroll, by beating Sasori a sand scroll (if a puppet scroll is made then substitute it for the sand scroll), by beating Hidan a life scroll.
Attacks: Yura's attack will be wind based, Kaze no Yaiba (Wind Sword). His stats will be the weakest of all the akatsuki since he is only a puppet being used. HP: 90% of the fighting shinobi, Attack: 95% of the fighting shinobi, Defense: 95% of the shinobi.
Clone of yourself: Everything matches your stats, an exact mirror of you, except he/she uses the attack, Satetsu Shigure (Iron Sand Bullets).
Each other member of the akatsuki will have a higher Hp, attack, and defense.
