(I'm sure Korea'd like to participate in that fight, but whatevs)
My version of a Philippines-wank was usually independence from Spanish in early 1800s->modernise->help America trade with China->go anywhere do anything. Yours sounds amazingly interesting of course, although I'd like to see a republic more than a kingdom.
it'd be a Philippines with tension alternating between republicanism and totalitarianism. like Imperial Japan.
my problem is my lack of sources on 18th century Philippines. tales of Andres Novales are few and far in between, and sources on his conspirators like El Conde Filipino are even rarer.
