Pilots didn't climb into their aircraft in the hangar, they did it on deck. Elevator animations are nice to watch, but on straight carriers, they don't occur at the same time as take offs and recoveries.
AFAIK, pilots are not to go into hangars or elevators, bar the one who is magaing the repair crews (in modern Navy, I don't know if they already had a pilot doing this during WW2).
What could be immersive would be get out of the ready room into stairs, catwalk, deck and then cockpit, but that's a lot of work for a feature many would skip quick.
