A one for one transplant of the scene from the beginning of the ride to predator cove won't work as the work necessary to set up the T-Rex/I-Rex encounter needs to happen.
My idea is to mostly keep the Predator Cove section up until the dropping box in JPRA, at that point the Monosaur scene begins and goes to the lift. We can see the damage the I-Rex did plus the Monosaur could be wound up after seeing the I-Rex.
I think the Monosaur smashing the glass is a good reason for us to leave the area quickly into a less desirable place.
Better yet, move that scene to the one before where we get knocked off course now. Keep the Predator Cove scene as is.
