It might be worth considering to add a static version of the ANZAC Class Frigate (similar to the FFAA mod´s BAM). While the current frigate is already a great asset, it is a potential death trap for anyone who wants to walk on it because of the engine limitations.
Having a static version that "only" features the working guns and doors would be incredible useful because it would allow mission makers to use the frigate without having to worry about losing half the infantry squad to ArmA´s engine problems. It would also make future and the already present (hangar) interior extensions more worthwhile, offering an additional (naval) base of operations to the LHD.
I know this is quite a big wish and should be tagged accordingly ;) .
