How about the Spanish seeks a ceasefire and promising the rebels to address their grievances?
Biak na Bato was already this agreement.
And how could the Philippines be included in the Teller Amendment?
Earlier POD with Filipinos recognizing US as a possible ally.
Hnw many Filipino expats are in the US at this time?
OTL, No one significant to influence USA. The closest thing you got of recognizing US as a potential colonial Asian power is Rizal with Philippines 100 years hence.
---------------------------------
A key to a more successful revolt is Rizal living and actually siding with the Katipunan. He has the intellect, the foresight, the influence among the illustrados, the middle class, the insulares, the mestizos(therefore the Spanish Army/Navy) etc.. which neither Aguinaldo nor Bonifacio had which is crucial in winning vs Spain alone or have a fighting chance against USA.
If Rizal dies as OTL, the best key to winning is the insulares siding with the Katipunan. They both have the same grievances as the Katipunan. An example of an Insulares is Manuel Quezon(who's father used to be in the Spanish Army), who only joined in 1898. Which is why 1898 was more successful since you got Insulares and majority of the people joining.
Make Biak-na-Bato a ceasefire agreement instead of a peace settlement. You'd just have to make the ensuing peace negotiations break down and you got yourself a return to hostilities (the War of Independence that you wanted).
There is no way this will breakdown. Katipunan already lost and have no means or base of operations after the Battle of Perez Dasmariñas. Aguinaldo was negotiating with nothing with his paper tiger Republic in Biak na Bato.
Like I said before, a more successful Katipunan means no Biak na Bato. Biak na Bato is the result of losing at the Battle of Perez Dasmarinas. Without losing there, Aguinaldo will still be in control of Cavite and be based in Cavite El Viejo. Winning in Battle of Perez Dasmarinas vs Jose de Lachambre is ASB as long as you do not have the support of the Insulares or any great power by the time of the battle.
