I feel like lately a lot of people have been taking "pulling a Meiji" as the country equivalent of going Super Saiyan
Dont get me wrong, I love this idea, "Industrial Sikh" just sounds sick!
But I think you'd have to extend that amount of time to 50 years are bare minimum
Reason being that while what Japan did IOTL was not in any way impossible for another country to do, specially as far as AH is concerned, it was remarkable precisely because they were able to pull that off at all while everybody else tried to slowly industrialized and even then most who tried ended up as overly rural client states of the imperial powers anyway
