I think the fact that Kara Tur is generally rather obscure at this point (the last time it got anything more than a passing mention was 30 years ago) and the fact its been a century since it was canonically described, you could do a LOT of revision while keeping the general theme of "Faeruns Asia" in tact. Only the most groggyest of Grognards will care if nations or cities get renamed, reinterpreted, or rectonned. Hell, I'm more interested in "AtLA x D&D on the the other side of Faerun" then I am making it adhere to a decades old box set, and given WotCs MO of redefining settings to fit modern sensibilities (Ravenloft) I don't think they would care either. They could make a whole new Asia setting ground up, call it Kara Tur and I'd buy it.The main issues for Kara-Tur were the use of local terms, usually Japanese, in general for the entire setting, even when it wasn't appropriate (like using "Samurai" in Chinese-inspired locations), and hewing too close to real-life analogues, down to at times just changing a letter or two in a real-life name ("Tabot" and "Koryo", for example). And, obviously, a massive dose of Orientalism. Those are fixable issues, especially given that there has been a over a century and two planetary catastrophes since the last time there has been anything published for the region. That gives plenty of wiggle room to make changes, while still being able to retain what was salvageable.
