I see where you're going on this Tommy, maybe refine it down a bit. Make it more similar to World of Warcrafts BG system.
Players in the pvp zone get a base participation credit for completing the event. Lets call these PVP points. Players who did well get more points based off how much damage they did or kills, similar to how money is awarded in missions now. More you shoot, more you get.
These points are then used on a "PvP Points Vender" in each countries capital where you can turn them into paints, blueprints and maybe like ship baubles like names, flags etc. Make the points 100% cosmetic so those who do well can show off, but not affect OW combat in super ships or mods.
Lets go one step further kill the pvp zone and create a lobby queue system that generates match ups based on BR and "leader board" rank and give each player basic ships and load outs to balance. No mods. No officers. mano a mano. same point awarding system as above. This will provide players with instant pvp action, but still not disrupt the OW balance.
boom, fixed naval action
