Assuming your hangar sided are one pixel-wide, that it will work. Hangars tend to get clattered along the walls. If you look at a car's garage, you'll se what I mean.
I think there is plenty of room for this large hangar to store 6-8 helos and all the maintenance stuff needed to operate them. The hangar sides go to the edge of the hull as drawn in the original drawing and one pixel is six inches which is a lot thicker than the walls would be. There is no need for a hallway or anything along the sides of the hangars as there is plenty of room under the hangar for people to get up and down the ship.
Also consider the effect of the helocopters rotors spinning side-by-side, on each other. Altough you have more than enough width for the helicopters to stand along side each other, i'm not sure, that such is the case with the rotors spinnig.
Yes there is space for two Sea Hawks to be side by side without the rotors touching. But I doubt they would land and takeoff at the same time because that would be pretty dangerous!
Space and volume is the one thing this 40,000 ton ship does not have a problem with!
