I was in the same boat about a year ago when I was figuring out how to add more aircraft to the carriers.
What I did is spawn the carriers at coordinates with some zeros such as
1000/20/1000 and 3000/20/3000 and had them at a rotation of 0/0/0.
Then I subtracted the height of the deck compaired with the water level and the carrier's floaters and got the y coordinates for each vehicle.
Starting from the center of the deck moving forward are the positive coordinates and toward the back of the carrier are negative coordinates.
The LEFT side is negative and the RIGHT side is positive coordinates on the grid.
So after doing the math of where each vehicle should spawn so that it will be able to take off easily the next thing I figured out is how to swap carrier spawners between the red and blue carriers and here are a few screenshots showing my carriers in Wake Island.

The RED carrier is smaller in comparison to the blue carrier so it took some time to see where each vehicle can take off properly.

The coalition carrier ( Nimitz ) has a larger deck to work with so I have all the vehicles spawning along the sides to keep the flight deck clear.

And it is also cool to have floating choppers where the exit locations wont get you in the water. lol

My version of Wake Island starts off with all the flags being neutral and the Navel fleets are in the opposite corners of the map protected by Destroyers.
Let us know how your carriers look now after you added more aircraft.
