I'd say around 2-3 million lifetime. I mean, even Kid Icarus: Uprising is approaching the one million mark, so Luigi's Mansion should be able to beat that by a couple of million purely by its name. In the end the legs will depend on the game's quality though and, as Soleron mentioned, having multiple mansions really isn't a good sign. Trading quality for quantity is not a good move.
