I know this is an unpopular opinion, but I say drop the coaster and bring either RC or Army Men in its place. It'll cut the budget of the land and satisfy the thrill aspect.
I mean, neither one is a great attraction, but honestly TSL is a lost cause as far as creating a really immersive land goes so I'd rather the budget goes to another area of the park to help capacity (which could mean Mickeys ride on a new plot), or even a second land next to TSL (and those who know me know how much I desire Monstropolis
).
