That's exactly one of the scenario I previously thought, although I'm still unsure if a quicker war of independence (mid-1897 to before May 1898) is plausible or bordering ASB already.
Well, you need to POD much earlier. You need to have all the Philippines resources in 1896 much like in 1898. Whatever happened in 1898 can happen in 1896 or ealrier.
That means more weapons, help of the ilustrados, help of all Insulares. The issue with the revolt of Aguinaldo or Bonifacio in 1896 is that either one of their organizations are not fit to fight a competent european/american army.
So the katipunan needs to include more illustrados, Insulares than OTL membership. Also, Your timeline in another thread of change of heart of the local garrison is also possible since this has happened since Novales revolt in 1823. So, a full or half Spanish army and navy fighting for the Philippines is a possibility, which considers themselves Filipinos regardless if they are Spanish blood. So any earlier POD until 1823 is even feasible but it wont involve Katipunan or any 1890s hero.
