>>i think it will yield the government a lot of money from tourist visiting and if voyages will be planned?<<
Nope....not a chance. And the idea behind any commercial enterprise is not to yield money for the government but a return on the investment capital risked by those who buy the shares of stock in the venture. The reality is that any faithful replica couldn't possibly be built in such a fashion as to comply with current Safety of Life At Sea regulations and agreements. Given that any faithful replica would almost certainly have to built with obsolete shipbuilding techniques with tooling that no longer exists and using hopelessly outdated technologies for propulsion, navigation, communications, etc...the ship would not only never be allowed to sail, but would be absurdly expensive.
To add insult to injury, the habitabilty standards...quite lavish by 1912 standards...would be unacceptable anywhere today, and would only apeal to what's called a niche market. Titanic/Edwardian era enthusists may well just love it, but the general public, which wants it afloat shopping plazas, en suite bathrooms, casinos, theatres, lounges, bars, game rooms, air conditioning, hollywood showers with no regard for water conservation and the like would never go for it. If anyone knows any bankers stupid enough to make the required loans, please let me know who they are so I can avoid doing business with them.
Most of the sites you asked about are long gone and for all the hoopla raised, not so much as a single plate of steel has been joined with another in the building dock.
