The Fw 190 as a carrier borne fighter is not going to work very well. It has a high wingloading, requiring a high take off and landing speed, too high to successfully take off and land on a carrier. That would have necessiated a major redesign and who knows what would have been left of its performance as we know it. In any case, it would have needed some time.
I think that the RN, USN and IJN would have gotten a lot better performance out of the CV because of operational know how. The Germans would have started from about zero - lagging 20 years behind.
