I don't think a CriclePacific fare is valid for your itinerary becasue you are not crossing the Pacific. There may be value in making it a BIG trip and doing a Round World OneWorld Explorer - I'm sure that you can fit that lot in - just don't get caught by the "2 stopovers in continent of origin" rule. Its cheaper to buy it in SIN or other Asian cities - you just have to get up there and back.
As QF WP said, go to the OneWorld Forum for help on ideas.
