I actually wonder if Scar and the hyenas will even be in the ride, save perhaps for a shadow projection ala Gaston and the angry mob. There's been a annoying trend in recent years where villains have been absent or heavily sidelined from kids rides based off animated films.
Dr Facilier didn't make it into Tiana, Hans is only in Tokyo's Frozen ride and not any of the other three variants. And his villain moments are relegated to two very crudely and poorly implemented video screens (shockingly bad compared to the quality of the rest of the ride i'll add). Mother Gothel isn't in Tokyo's Tangled ride at all. Gaston and the angry mob are shadow projections shoved into the background of a brief transitional scene. Then there are examples such as California's Snow White ride (which used to be almost identical to Paris') receiving an overhaul that significantly brightened the entire attraction up, removed a lot of the scary scenes and setpieces and drastically toned down the scenes with the Witch.
That said, these are all princess rides and Disney were trying to make them appeal more specifically and exclusively towards little girls (a mistake, but one I won't get into here). So I wonder how they will handle an IP that arguably has more of a male-centric appeal such as Lion King. Captain Hook is still given a prominent role in newer Peter Pan attractions, an IP that attracts a more gender neutral to male-leaning demographic. Though Hook is much more of a silly and not all all scary comic relief than a lot of other classic villains. Scar and even the hyenas are very different, they stand among some of Disney's most most violent and dark animated villains. Even their more comical moments are tinted with extremely dark and violent overtones.
