Allowing the captain to delegate control of one of the ships AI crew to one of its actual crew, that crewman would then gain access to F1,F2,F3 and have their V commands switched to the ones captains get when on helm (not being able to "I'm getting on aft guns" will be a huge loss but I'm sure they'll cope). One AI would then respond only to the captains commands and another only to the delegated crewman's commands (unless used on a 3 crew, 1 AI ship for whatever reason in which case only the crewman would have commands).
Possible uses:
Pyramidion - Engineer sets their AI to "man the fore guns" and takes the balloon side, captain alternates between "repair the armor" and "repair the engines"
Mobula - Engineer takes hull side and alternates their AI between balloon and starboard guns, captain sets theirs to man fore guns, engine repairs are done case by case
Goldfish - Gunner alternates their AI between manning side guns and repairing the armor, captain keeps either F3 or a mix of balloon, armor and engines.
and so on for other ships.
It would allow for a much wider choice of ships and setups when only 1 crewman is available without making the AI overpowered in any way. That in turn would allow many lobbies to go to matches faster rather than waiting several minutes for new crew.
