So the question is, am I crazy?

If so, tell me how I can get another modern fleet carrier without shelling out 40-45,000 tons?

Addition of the first two production steam catapults and to service them, a new modern high-pressure steam plant (I've devoted 5,000hp in the SS report to boilers to maintain speed when using them)
