You could take the game play from SOCOM: Confrontation for PS3. The VIP mode is where you have 2 teams 8 vs. 8 with 3 VIP's. The SEAL team's job is to escort the VIP's to 1 of 2 locations and they can be split up (i.e. 1 VIP to location A and 2 VIP's to location B and vice versa) that way the entire opposing team can't camp 1 escort site... Well, they could it just wouldn't be very wise... The goal for the terrorist is to eliminate either 2+ VIP's or the entire SEAL team. The SEAL team's objective is to either eliminate the entire opposing force or bring 2+ VIP's to one of the extraction zones and hold them for 30 seconds for the extraction chopper to arrive and evacuate the VIP's
8 minute time limit
No re-spawns
VIP's kill hit has to be center mass or head shot, that way a lucky bb that nicks a leg or arm doesn't kill the game play, otherwise it would be waaay to easy for the terrorist. In the actual game, the VIP's carry heavy armor making it harder to kill them and it's still damn near impossible for the SEALs.
