I personally would make this a totally new and totally wet ride.
Have waterfalls, fountains, waves and other things which can make the ride really enjoyable.
Possibly include a long walkway like Battle Galleons for other park visitors to spray the riders.
However if this was to happen i would want the water to be cleaned ALOT
The water in that ride and the lake is a horrible colour and wouldn't want to get a mouthful, that goes for Stormforce 10 aswell. The water could do with being drained, filtered and filled back up again
