In theory I agree, though I wonder what they could do with Lion King in ride form other than some kind of book report. Aladdin had a few obvious possibilities for rides, but Lion King is a bit harder to imagine for me.
I've always wondered whether part of the reason we've never heard rumours of Lion King rides (until now) had to do with the difficulty in recreating the scale of the film. It's one thing to be weaving through a castle or woods, but the African savannah is a little harder to recreate. The only real way I could see it happening is with scenery close up and screens in the background, which could also end up looking a little lame.
As for the land, the best analogy I can think of is how you create a land themed to dinosaurs. Universal has gone with a theme park bringing dinosaurs into the modern world, and Disney a tourist town that has sprung up around an archeological dig. A land set back in the time of the dinosaurs, however, seems impossible to pull off believably as you couldn't include any obvious human structures. The same, presumably, goes for The Lion King.
Definitely agree that a Lion King land/attractions lacks an obvious route, that said, a Dinoland or Lion King could be like Camp Jurassic at Islands.
Surround the land with building-high rock-work or dense foliage, with the centerpiece being a nice water feature. Put shops and restaurants within caves, or rock overhangs. Think mermaid mermaid queue and the backside of 7DMT.
Lion King would be the same, except I don’t think building more than a mini-land would be smart. Just build pride rock as a centerpiece, have the attraction entrance be on the right side, exit on the left with a big shop built into the rock work. Have a restaurant embedded into a hill where pride rock is facing, or build it off to the side into an elephant graveyard or call it a waterhole and build it around a small lagoon and water feature.
I really don’t know what you would do for the ride vehicle, I honestly think a water ride works the best, because a water ride isn’t an animated object, it could be driftwood in a stream. Go through an ambient graveyard. It would be cool to enter a cave, have dark ambient lighting, then have scar walk out from above and try to recruit you to overthrow the king.
Scar is easily one of the best villains, so would be a good way to maximize his inclusion. Then you could have a couple hyenas throughout the line or initial part of the line, go to an elephant graveyard, then run into danger, have Timon, Pumba, and Simba rescue you from a waterfall. I imagine doing like Maelstorm, but instead of being backwards orient you forwards and have it overlook the pride lands, and then have side-track switch that takes you to a completely hidden area or a pivot switch through a dense jungle. Pumba could run and headbutt the side of your raft and then have you put in the jungle. You could have them do some Hakunah matata stuff, then eventually return to the pride land with a climatic battle with scar where you actually do go down a large drop where where you have another scene or two, like with Splash and then have the ride end.
