I would love to see a high capacity high thrill coaster in this plot. It would help with crowd management to have a third major coaster in the area to draw some of the crowds away from Steel Vengeance and Maverick when their lines are long. Plus it would help distribute the crowd every time one of those two dumps their queue because of maintenance headaches.
Edit: so maybe NOT an extreme spinner, unless Mack can figure out how to triple the capacity of Ride to Happiness. According rcdb, RtH only does 550 riders per hour, which is even worse capacity than Maverick.
