Guardedly optimistic is my take on this latest plan.
There are a number of obstacles to overcome. While I have no doubt that structurally the United States is sound (it was built to military specs, after all), the infrastructure is a big issue and potential deal-killer. The powerplant was state-of-the-art when built, and she was phenomenally fast, but that was decades ago and the engines have many miles on them. Then there is bringing the electrical, mechanical, water, etc., systems up to where they can pass modern inspections. But doing all of that might still be cheaper than building a new ship from the ground up, and there are the nostalgic and cool factors that come into play.
As the saying goes in Monty Python, "I'm not dead yet!"
