I imagine that this would rather naturally lead to Burma managing to attain a status similar to that of OTL Japan
Eh... This assumption seems unfounded to me. Two statistics showing how Burma was critically lacking in terms of both preexisting urban networks and a labor force:
- In 1800, Edo (capital of Japan) had over 1,000,000 inhabitants, with other cities (Kyoto and Osaka) in the range of 300,000~500,000. Amarapura (capital of Burma) had more than 100,000 inhabitants. No other city in Burma had a population of over 20,000.
- In 1800, Tokugawa Japan had around 30 million people. Burma had a grand total of 2.5 million.
The only real advantage Burma has over Japan is its ridiculously high literacy rate for adult men. But literacy in itself doesn't do much for industrialization, especially since Burmese popular literacy was due to Buddhist monastic education rather than state-run programs.
The best evidence that Burma could not "Meiji" is the fact that your scenario
did happen with a society very similar to that of Burma. This is, of course, Thailand, which remained independent but failed to become a regional power. And logically, an independent Burma would fare
worse than Thailand. This is because of at least three reasons:
- In 1824, the most powerful empire in Southeast Asia was Thailand, not Burma (or any European power, for that matter). So Thailand had a stronger base of power from which to negotiate its place in the new world system.
- The Thai heartland (Bangkok) was right by the coastline. This meant that any would-be European colonizers either had to conquer all of Thailand in one big gulp or none of it; they couldn't just detach the coast from the interior, as they did in Java or Hyderabad or countless other countries. Few European powers were willing to take this risk. By contrast, the heartland of the Burmese empire was in the interior, which meant Europeans could conquer the coastal areas first, wait for the coast to be absorbed into the empire, and then conquer the weakened rump state. This is basically what happened in the Second and Third Anglo-Burmese Wars.
- Burma was right next to Bengal, the center of British power in Asia.
Things could have gone (much) better for the Konbaung empire and for Burma in general, but Meiji-ing is not a plausible option.
