I can see Apollo sitting off to the side smugly watching people being turned into Pokémon and being happy that they get to see things from the other side. And possibly going out and capturing people he thinks treat their Pokémon badly to show them what it's like. XD
As for Kanto... in Gen II/IV it really doesn't have anything going for it to begin with. The only thing I can think of it the Pal Park, and in Route that would really be just another Safari Zone with different Pokémon to catch. Poking around Bulbapedia for ideas of what could go there... Contests, Pokémon(-riding?) races (land/sea/air/triathlon?), a chance to challenge Red, special items, capture challenges (catch a provided wild Pokémon the fastest/with highest remaining hp/with the most style/whatever). Not sure how workable any of these are, but throwing them out anyway (while knowing that I wouldn't see the benefit of most of them just because of who I play -_-).
