No, but this is the era of digital technology, CGI, and there's a couple little somethings called stand-ins and stunt doubles. It could be done, easily.

No, it couldn't.

Unless you think CGI has advanced far enough to make a convincingly realistic and expressive dancing Carrie Fisher, then that's a load of crap. You can only get away with so much with cutaways and body doubles. The entirely new aspects of the scene as you've written it involves seeing Leia's face and expressions.
