Step 1:
Remove Dragon Challenge but put it in Storage
Step 2:
Gain rights to Game of Thrones for theme park use
Step3:
Build Game of Thrones land in new 4th gate with 3 to 4 rides around a sea. The forced perspective opportunities are incredible.
Step 4:
Have B&M build a third track to compliment the other two. (Or just build a new coaster with three tracks) for a ride bases on Daenerys' dragons. Station and queue would be Dragonstone. Ride would include props as targets for the Dragons to attack complete with them getting roasted via pyro.
Another ride would be a large scale Mack splash battle with ships that had a capacity of 20 to 24 for a sea battle with Kings Lang in being a part of it.
