Since most Emissaries have some voyages to go with them, I thought reapers should have one too, but in the form of bounties. You would buy the voyage as normal and vote for it as normal. The game will select a random crew on the server to be the bounty, and they will be notified a bounty is placed on them. The Reaper crew will be given a reaper wayfinder to locate the crew and will have a certain amount of time to locate them, and sink them. If they are successful, the reaper crew will get some bonus loot and gold on top of the loot the crew has on their ship.
Notes:
-Emissaries would take priority since it's the main thing reapers go after. But if there is no emissaries, then a random crew will be picked at random.
-If the bountiee crew gets sunk by PVE, or disconnects, it will be count as poached, and the reaper crew will receive less gold and loot.
-The player crew will be given a tool to show how close they are to the bountee (and the reapers ship location will be hidden on the map).
-If the bountee crew doesn't get sunk in time (aka survive in time) or if they defeat the reaper crew, then the bountee crew will receive some gold and some loot as a reward.
-Multiple bounties can happen at the same time.
This idea is a concept, and the idea is welcome to be changed and adapted.
