This was poster several months ago, but I just had to reply. Son, I can think of no greater calamity that could befall you then to get caught in either the PI or Thailand with any kind of fake document. Even after explaining and possible getting cleared (more likely to be sent bank with rejected in your passport) You will get posted on the watch lists. You will then get extra scrutiny each and every time you travel. It is not worth it.
Get all your documents in order, dress the part, keep cool and calm, be patient and 99% time no problem. I have travelled all over Asia for over 40 years without issues that way.
