Since terraforming is definitely allowed you forgot to mention that 'SFH' (these guys again...) probably will purchase the complete Dutch Alps (also known as 'The Dutch Mountains') and relocate these to their park as an additional anniversary event.
Since (to my knowledge) this would only make a truckload or two of material we thus should be very carefully when applying any terrain. Instead most of the terrain should be water. At least i think so...
And now i am hoping very much that no one is offended by this...
