I would much prefer to see her remain as is. You could still do some minor alterations to her exteriot to cater for larger helicopters and no body would really know. But as for using her existing powerplant to provide power to the ship, well seeing her last hull survey she go the golden tick of good health, why don't they send her back to work traveling the high seas, there was never a shortage of numbers wanting to travel on her. But I fully agree on leaving her interior as is.
If the Arabs tried to scrap her, there would be an even huger battle than there was over the SS France/Norway/Blue Lady.
