The suggestion that Jungle Cruise belongs at Animal Kingdom is ridiculous. The ride, as it is today, is perfectly suited for the Magic Kingdom.
The idea of a boat ride showcasing animatronic animals going to a park that's completely based on animals is far from ridiculous. The ride, in no way, is at all suited for the Magic Kingdom. There's nothing "magical" about it, it has no well known characters, and has no basis on any Disney film.
