Getting to as-launched condition is hugely complex.
For one, the ship would need the 12' of hull blisters removed.
Also, the entire 5"50 complement was casemated in the hull, about half on the 100 deck, and the after guns on the 200 deck.
Most of the superstructure, other than the armorned conning tower, was different, too. The Wardroom, the Goat Locker and the like were moved through the course of the refits (the Officer's wardroom spans the area once inhabited by the second pair of 5"50 casemates. The Galley reamined on the main deck, that would be about it.
Getting a set of plans for the crane-top gun tubs for the 1 pounder QF guns will be interesting, too.
About the only thing that would be left from the Trumpy kit would be the main gun turrets and the 5" 50s, and perhaps half the boats. The hull & superstructure would be largely scratch-built, so, you'd be buying bits off the aftermarket as is.
Last word is that Texas is in a shipyard in MS. How the State is intending to spend the 25 million and the later 35 million earmarked for her preservation is yet to be established. All manner of speculation abounds. Seawolf Park in Galveston gets a lot of traction, but that would need millions in dredging to be deep enough (and there's a sunken Liberty ship in th way, too).
Down by Lexington also gets a lot of traffic, but, there's, again, not much room for another vessel of battleship size.
Especially given that everyone is pretty much agreed that she wants a dry berth rather than being in salt water anymore.
For my 2¢ I'd like them to use a location near Surfside, or, even better, right off Clear Lake, to be near NASA. Bother would be suitably sheltered locations in the face of Gulf Tropical storms (which severely complicate the Galveston and Corpus Christi locations).
Texas rode out Ike and Harvey with little or no damage in the San Jacinto berth. Here issues there were with the interfaces of the wleded bulges and the riveted hull, and that all the plumbing in the bulges had been (short-sightedly) ripped out in 1947. Which makes keeping them pumped out an issue 72 years in the making.
Texas is special in many ways. She was the very first USN ship specifically meant to be transfered into monument/museum status. Every other 'display' ship has lessons learned from Texas. And Texas was meant to have learned from Olympia, Oregon, and the like.
