The Mughals to me already feel like modern India "like" with a Stepwell improvement, Sepoy UU, and Delhi as their capital. Qing China basically has all the modern-day spellings of Chinese cities in its list.Prussia is already Germany in all but name so (unlike America) that's actually an easy fix, and China is troublesome because there's already three China in the game, mind (so who really should get the actual name?). India is the trickier one, I will grant.
Along with Prussia being essentially Germany too, it's hard for me to think of compelling designs for later civs that would be interesting and distinct enough.
