Yeah I think the tour is too liked by the GP (and has been since its inception) to be removed. Not to mention it would create an almost unsolvable capacity issue if it was removed (the wait time + ride time is a 1.5-2 hour investment for each guest, not to mention the trams hold a ton of people and are dispatched every few minutes).
To speak to Kong specifically, the Peter Jackson Kong is TWO Kong iterations old at this point. I wonder if a proper Godzilla vs. Kong attraction would make sense to replace this part of the tour. Might be tough rights-wise, since WB releases the GxK movies. Not even a big fan of the movies myself, but I am a Godzilla fan, and I think the movies do well enough to justify an attraction.
