Not sure if you wanted to include Australia or were only doing it to go to POM but I believe there are flights between MNL and POM which is also a seperate tkt on PX as you have it now. So another way could be SFO MNL SFO on PX using a net fare of even at a published D, and then a seperate tkt MNL POM MNL which in MNL will likely be less than finding it here on-line
But of course not as many OW miles
Have fun
