Up until a month or so ago, the short answer to the first part of your question would have been a simple "no," but with the late-October announcement of Lucasfilms' purchase by Disney, a company that in no way could we conceive of wanting its brand associated with Las Vegas, that now has to be a resounding, "hell, no!"
Backtracking to the summer of 2011, the word on the street was that there were plans afoot for an 18,500-square-foot attraction on the site you correctly refer to, which was the former condominium sales office for CityCenter, called "Star Wars: Where Science Meets Imagination." The company behind the concept, which was proposed as a showcase for models, costumes, and props from the film series, was called Order 66 Entertainment - a reference fans of the movie franchise would recognize from "Episode III" - formed by a real-estate developer called Jay Bloom. MGM Resorts International confirmed at the time that they were in tentative talks about the attraction.
To anyone who follows the entertainment scene in Las Vegas, Bloom's name may ring a bell, as he was also one of the original managing partners in Murder Inc., the company behind what debuted as the Las Vegas Mob Experience at the revamped Tropicana earlier that year. The much-hyped attraction filed for bankruptcy protection just months after it opened, having scaled back its interactive element (the equipment involved was apparently never paid for) and slashed ticket prices for what was reduced to a collection of artifacts that attracted only a quarter of the projected number of visitors.
Things then started to get nasty, with accusations by principal debtor Louis Ventre that Bloom had fraudulently channeled assets from LVME into his personal Star Wars project. Bloom was forced to relinquish his ownership interest in Murder Inc. and was slapped with numerous lawsuits claiming breach of contract, fraud, and concealment.
To cut a long and murky story short, having filed for Chapter 11 bankruptcy protection, the Experience passed to new ownership (the same company behind the Da Vinci exhibit currently on display at the Venetian), which fully revamped the exhibit, renamed it the Las Vegas Mob Attraction, added significantly to the collection of artifacts, reinstated an interactive element, and rescued it from potential oblivion. When it comes to Mr Bloom and his Star Wars dream, however, we've heard nothing since the whole debacle took place -- nor are we likely to, given the more recent events referred to at the beginning of this answer.
On a more positive note, you'll find discount offers for both the Mob Attraction and Da Vinci -- the Genius, both of which we can highly recommend, at our couponsinvegas.com site.
