A carrier listing (it's called listing, not leaning), would have an effect on flight operations from the carrier. A carrier needs to be near-death before a list would be effected. Lists are also not fixable without some sort of damage-control and counter-flooding capability. That would have to be coded in. Anytime a game carrier loses its ability to launch aircraft, players will move elsewhere, and the carrier will basically be lost unless someone cares enough to move it out of danger. Until there's a way to save the carrier and have it repaired, that ain't gonna happen.
Loss of steering control on a fleet carrier requires huge amounts of damage to the innards of the ship, not just the flight deck area. Steering gears rooms on an Essex class carrier are 5 decks down, and steering can be accomplished with engines as well, although this would also have to be coded into the game. Chances are, you'd be more likely to effect steering damage with a torpedo hit as opposed to a bomb hit.
Unless you have an aircraft on the deck heavy, ord is brought up from the lower levels (5 and 6 decks down) to the hangar deck, where the a/c are prepped for the mission. They're fueled and armed on the hangar deck then moved to the stern of the flight deck for launching. Aircraft recovery is the exact opposite...aircraft are wrangled forward and the stern cleared. This was standard procedure for US carriers, who did it differently from RN and IJN carriers during the war, who a/c were typically armed on the flight deck (hence the loss of 4 at Midway).
Flight decks of US carriers were not armored, as a result, holes were encountered. Damage control parties were experts in patching up flight deck holes to resume flight operations. In the game, a hole in the deck means no air ops, so players will be forced (or will try), to get airborne by launching around the holes, or, once air ops are suspended, will ditch the carrier, move somewhere else, and allow it to be sunk.
