There are 9 HK + 5 Gorosei + 3 Admirals + IMU + Sengoku + Kong = 19 Fighters
There will probably be 9 SH + 5 Revo Commanders + Sabo + Dragon + Luffy = 16 Fighters
If Saturn and Kizaru loose that brings it down to 17. Sengoku and/or Kong may also not be around or there may be a 10th SH.
Dragon likely fights IMU
Luffy fights Akainu
Sabo fights Topman
Zoro fights Venus or Garling
Sanji fights Mars
Fujitora fights GreenBull
Rest of the SH and Revo Commanders fight HK, Admirals, and Gorosei depending on their strength level.
Then Dragon looses and all Luffy fights IMU after him probably alongside Sabo after he beats Topman.
