I think if Universal truly wanted to invest in the park and expand, they'd find ways to make it work. They have in the past with BTTF and Jurassic Park. While some land is definitely unusable and too steep and crazy, I definitely see potential in somw other locations. But that's all way too far in the future probably. I'd think they'd want to resuse other locations for new attractions first, like SES, WaterWorld, etc.
