Kings Island did this to the Flight Deck/Bat during the retheme. There was a section of rail that was cut out and replaced. Never heard a reason, but I assumed due to rust or deformation. I'm sure it's not the only time its happened. No reason to think it hasn't happened on a B&M at some point.
A Wing Coaster would pretty much mean tearing out the entire station and launch tube and rebuilding from scratch. Pretty sure Wing coaster track is wider than standard too, so it would have to be a complete do-over.
Not much about this rumor make sense. I can't see a complete retrack. Maybe sections, or even redoing parts of the ride completely, but not replacing all the rails. The only types of trains that makes sense for the current configuration are sit downs and floorless. New sit down trains is a reasonable choice. But then to spend all that money and time to keep it Hulk is odd too. People will just think its the same ride. I'm intrigued by this whole deal. My gut says its just an extensive rehab and train replacement, but stranger things have happened.
