It's legal as far as I can see with the caveat that the SYD-HKG-LHR must be a transit in HKG, as must all but two of the stops in N America. Flying JFK to HKG (CX) would get you more miles for the transpacific leg, and LHR to LAX similarly on the way back if you can rearrange your N America segments to fit that.
You can also get more miles by:
- flying HKG-AKL something like this for max miles in Aus: HKG-AKL-MEL-PER-DRW-SYD-LHR
- in Asia there are a number of longer runs than KIX and DPS: consider KHI, CMB, BOM or CTS though KHI & BOM may require visas.
