The lowest AMS-BKK-AMS fare is not that much cheaper than the lowest AMS-PVG-AMS fare. There's about £200 round-trip in it, so only about £100 more to do PVG-LHR-AMS inbound rather than BKK-LHR-AMS. Not worthwhile given that you have to position from PVG to BKK.
However, thinking about small permutations to this, you could shave off rather more by flying AMS-LHR-BKK // PVG-LHR-AMS. That would save you about £330 off what you originally thought of, which is probably comfortably enough to make it worthwhile for you to get from BKK to SIN by some other means.
