I can easily see them changing the Mandarin's ethnicity, too.
Wouldn't that also mean changing his name?
The Iron Man writers really dislike using code names for some reason. Iron Monger and War Machine were only used once in a sentence, easily missable, while Whiplash and Black Widow were never named onscreen.
That's why I see them going with Gene Khan instead of Mandarin, which would be fine for me.
