I say do forbidden forest and end it there. Take our Dragon Challenge, add an indoor coaster, (i wish it could be exactly like Taron) themed to the blue car or whatever it is called (seriously just a mind boggle at this point) and a family interactive ride, and a great hall didninf experience to round it all out. Boom! You got everything you need. I don't believe you could do ministry of magic as a ride tbh. I think Fear Factor would be a much better spot for an inhouse IP (if that's even remotely possible anymore) and then start with your third theme park (no I will not be calling VB a theme park). Expand CityWalk with fun things like go karts, rope course, laser tag, indoor skydiviving, and cheaper places to eat as you have City walk completed for the next 5 years. Add the SLOP ride in the Toon Lagoon. Expand JP with either a roller coaster or dark ride, make lost continent something much better, like maybe a completely original IP and UNIVERSAL BEATS DISNEY
