Very good idea, I can’t wait to participate in such event; however, I got an idea that might do the balance which is allowing only 2 or 3 each for Gangs and Squads allowed to participate in that war.
Might be like - meeting point(maker) for each of the ships and the minimum required players to earn the ship would be for example 5 from the same Gang/Squad. (No DM should be allowed I suppose?)
So the first 2 or 3 Gangs/Squads to reach that assembly point would be the host for one of the ships and so on.
I am just trying to find a way so criminals won’t outnumber cops, as usual, as @Absent mentioned. And we don’t need to worry about DE/CLO as they always balance their owns.
OR
place 2 makers for Gang/Squad members to enter. If there are at least 5 players (different gangs or squads) in each marker then dispatch each group in a ship, hence players from different gangs and squads would be able to participate equally and there wouldn’t be strict priorities.
