Checked a few possible early 2017 dates for WAS-BKK. Cheapest GPU-able on NH class is B for those dates. Spread between B and P is ~$600 r/t.
4x GPUs are worth more IMHO than $600. I'd just pay the higher fare; I mean, we're talking at that point only a 14% premium or so to pay for business over economy.
It may make more sense on other routes, FWIW. The fare difference spread on IAD-NRT nonstop operated by NH in B vs. P is over $1k r/t, and would be 2x GPUs.
