It would be awesome if they'd do that, but I suspect the logistics of security clearances for individual civilians to come dive that kind of a government facility would be daunting, at best.
Last I had heard, they were considering opening it up to commercial contractors for industrial applications. They can have a lot more control over that and bring in significantly higher cash flow, rather than charging you and me a couple hundred bucks. They could also do that without having to alter their work schedule to accommodate recreational divers.
