For Luzon you can create any ruler name, with any indian/malay name...who could unite the states in Luzon not having the Philippines remain uncolonized would cause Limahong's invasion of Pangasinan to be butterflied, if he still arrives Limahong will sack Manila and establish himself there paving a way for a Hindu/Pagan power taking over the island at a later point.Wait, so whats your take on this map?

"Well, as far states go there wasn't much I could find without going into speculation. The rulers of Cebu and Tondo are speculative, Batan is at least a son of Bunao, also known as Lakan Dula, with Cebu I'm using the name of a prior ruler because I have no idea if this person has children or what names I could use. "
I used this in my TL, where things go south, and the Spanish do not colonize the Philippines, what exactly would you make of this map, in terms of an attempt at accuracy? I'm not exactly aware of too many powers in the north of Luzon Island, but this region isn't my strong suit nor could I find easily readable sources in English, when it's my only language.
