Now I don't know much about drving ships but will anybody in the RN have the skills to handle the big CVFs?
As for the aircraft I don't think it's an issue as they'll be flown by the RAF as there is absolutely no requirement for them to be RN piloted when their task is projecting air power ashore (which is an RAF core role). Not a wind-up WEBF just a pragmatic dose of realism; does it really matter which Service the pilots are from and which Squadron markings are on the aircraft? I believe their are savings (efficiencies) to be made by having the whole fixed wing cadre in the RAF.
