I have to wonder why Sabo, Figarland and Aokiji are in there. They're not the leaders of their own factions and are subordinates to Fraudgon, Imu and Blackbeard. They've also never shown much interest in getting the One Piece, same with Fraudgon.
I guess Figarland is a leader of the Holy Knights but he's still a subordinate to Imu and may only want to find the One Piece or stop others from finding it on Imu's orders.
Akainu has shown rebellious tendencies, so he may split the Marines from the WG at some point and will want to find the One Piece to destroy it.
Fraudgon has never shown any interest in the One Piece.
Neither has Aokiji and he's loyal to Blackbeard, unless of course he has his own goals in mind with some 8D chess keikaku.
Coby I guess is Garp's successor and he might become head of SWORD or the marines one day, so it figures he'd be aiming to find the One Piece before Akainu and any pirates, but for now he's still just a high ranking SWORD agent and hasn't openly shown interest in the One Piece.
