The only thing they really change up is the Rings, which are given a new meaning as a terrorist organization instead of a bunch of space alien rings. But they trade the power of the Rings for the power of Extremis, which is equally as powerful and menacing, and blends nicely into the Extremis plot without having to explain an over-the-top, jarring backstory about dead dragons in flying saucers and alien magic rings.
Honestly I've made my peace with the twist, and I find the reveal scene hilarious. While I would have rathered a Mandarin with the rings, Killian is a badass villain so I'm happy with him regardless.
Also, I find the name "Killian" more threatening than "Mandarin".
