Grizzly River Run at Disneyland Paris?

Here is an interesting piece of news! A mysterious poster on these European discussion boards presented this piece of concept art for adding a version of California Adventure's Grizzly River Run to Frontierland at Disneyland Paris.

Certainly more appropriate to the theme than Splash Mountain, which is full of cartoon characters- and I'd hate to see the further cartooning of the lands there. However, a rapids ride is full of water, much more so than Splash, and Paris has very cold winters. I've been there in late October, and it is already cold and sometimes harsh. So, we shall see how this plays out.
