The original flight deck arrangement of the USS Forrestal wasn't all that different as originally laid down, so I expect the United States to look very similar to the OTL Forrestal class. The only real question is whether the USN would be able to work in enough magazine space to carry a usable warload of conventional munitions.
Probably the only way for the United States to escape cancellation would be if she was suspended at an early stage of the building process to allow the USN to complete her to a similar standard to the Forrestal Class.
I had not thought about that possibility, from what I have read about them they were primarily to be used for nuclear attack however they also had a secondary role for ground attack and the like. That being so why would there be an issue with magazine space?
