Interesting. The city replacements are cool. What's the point though? Climate doesn't exactly align with latitude, and has other factors. Lifestyle, food, culture would also not depend on latitude.
I travelled from Sydney to Cape Town a while back. Both cities are roughly on the same latitude, and it shows.
The climate was similar, temperatures were similar, even the type of vegetation that showed up were similar. Trekking through South African veldt felt much the same as walking through Australian bush
I had the same feeling when I lived in Porto and later visited San Francisco. The two cities have so much in common: similar temperatures, they're both famous for their bridges (Porto actually has several), the fog that rolls in regularly, and even their most iconic bodies of water both have "gold" in the name: the Golden Gate and Rio Douro (which means "golden river"). I think this comes from how the water looks golden at sunset, since both coastlines face west. And of course, both cities are known for their cable cars.
