First, thanks for the comments earlier.
This is my second real effort at the same ship, focused on hull form. I expanded the beam slightly and cut some length. Draft remains 6.25m, as that appears comparable to OTL Wasp and Ranger as listed on Hazegray.
Since raising the freeboard from 5.92m to 7m was an issue on the first version, here's how I approached it :
Freeboard was raised 0.1m from default (5.76m to 5.86m), from stern "2" to "11", then the 1.6m ave 10% ramp of "12" to the bow, which is the default 9.06.
Now the tweaked ship :

Misc : SQRT (3136) = 56 aircraft
Vessel will be declared as 15,000 tons, but in truth is 0.5% over ! RAM said he wanted to cheat on the CVs, he'd be so pleased
Freeboard was raised 0.1m from default, from stern "2" to "11", then the 1.6m ave ramp of "12" to the bow, which is the default 9.06. Draft remains 6.25m, comparable to OTL Wasp and Ranger.
Lower hanger has 100' flying off deck forward ramped at 10% and two catapults.
Primary use is meant to be unassisted fighter launch.
Main flight deck is 630' long. Two elevators are provided, one forward of the last crash barrier, and one prior to the first crash barrier.
Weaponry is arranged with 4 twin 125mm mounts fore/aft of the island, and the remaining 8 single mounts in galleries below the flight deck fore and aft, much like CV 6's 5" guns.
