It looks like a routing of BOS-LHR-SIN-PER-BME-ASP-DRW-DPS-HKG-(NRT)-LAX-BOS would work for you. The NRT stop is optional as you can do HKG-LAX direct on CX. This would be a 4 continent OWE ticket.

Also, you can save about US$1,500 (assuming the U.S. dollar doesn't continue its decline) if you originate in YYZ, i.e. do YYZ-BOS-LHR...LAX-BOS.

(Editied to add the ASP transit as JohnAx noted that the BME-DRW segment is not on a QF affiliate. You could also go back to PER then to DRW or do BME-MEL-SYD-DPS.)
