Whether you board a brand new cruiser fresh out of dry dock or a aircraft carrier built in the 1970s the uniform is the current dress. Just because your in command of a 40 year old ship doesn't change the fact the the crew would be dressed in the current dress.
Perhaps until they add more features you should wear the same current day uniform if it bothers you so much? Afterall, you got a antique ship/bridge and not a time portal to 2370.
clearly you've never seen any of the crews on the old ships in the US... like the Constitution... they use period dress with the exception of certain crew members.
