There’s way too much grade change in there, that entire section slope down more than is practical for this ride. I agree it would be a good fit in the lineup and I guarantee you they looked at it, but I’d be willing to bet they came to the same conclusion I have: it doesn’t work in the space
This would be like a 1:1 swap of Tidal Force for a new Power Splash, with a little extra elbow room.
I am more inclined to see the area grow with additional waterslide capacity (especially for Fast Track guests, which directly translates to profits more than anything else) over another signature ride taking up a huge footprint like this.
