With a POD in the 18th century or later make any of these states "pull a Meiji"?
- Afghanistan: their are generally two points I can see this working. Directly after the death of Ahmad Shah Durrani (maybe a more competent son inherits the empire), or during the 1820s - 1830s.
- Maratha empire - generally anytime before the BEIC became too powerful would be plausible.
- The Sikh Empire - I don't know particularly much about the Sikhs, so you would have to fill this in yourself.
I didn't include the Mughals because by the 18th century they had long decayed.
Bonus points if you can do them all in the same TL
