As for getting a regularly scheduled DDG or something, DLQs would have to move out of the bay. Would you really want to test the mighty single engine Sea Ranger out in the Gulf? Or the JP-5 trained, ship's company engineering folks hot re-fueling the aircraft with no high-pressure shut-off/safety? No thanks.
Concur. But what new fleet challenges are there to be learned before the FRS? There is a reason that the HT syllabus hasn't changed much over the last few decades - it works and continues to work. The three services have distilled a pretty solid syllabus that makes a basic helicopter pilot who has been exposed to almost all helicopter employment methods and who is ready to learn his service's specific aircraft, employment, and tactics. The purpose of HTs is not to make a fleet co-pilot - that's the FRS's job.
