1. That plan is not optomized for the tail number to be flown (could make it better or worse). and 2. Landing with 1:12 (1400#) seems like plenty of fuel in a Hawker. Its over 10% of the total fuel capacity. Look up 121 regs (worse than part 91) and you'll understand. Of course, I haven't seen the drift down so I can't comment on that.

It is interesting that no one seems to be bothered by thought of flying a Jetstar or G2 to PHNL. Although their ranges are quite similar to the 800XP. A couple hundred miles either side of it fact.
While that routing does require careful planning, it is do able. In some aircraft you would not be able to do it every day of the week. And you have to know that particular aircraft. The book figures are a guide only. Some aircraft do better, some worst.
As for knowing your particular aircraft. Keep track of oil consumption. I wouldn't do that route with any active MEL items. O2 topped off. Large capacity bottle or additional bottles installed. You would want at least 3 hours of O2 for every one on board.
Next, there are much worst routing in the world than this one. Just because it is water, doesn't mean it should be a terror. The Sahara, northern Artic and Hymalayias cause me more concern. As for options on the North Atlantic, look at the approach into Narssarssuaq (BGBW). Would you like to shoot that approach at night? I would prefer not to.
As for this particular trip, if it is not a regular thing like much more that once every year or two, I personally wouldn't be too concerned. As long as I was able to retain enough flexibility to conduct the flight to the maximum level of safety. The owner needs to have it explaned to him that while the aircraft is capable of this, it was not designed for this type of operation and that there are limitations to the regular conduct of this type of operation. Add the fact that you might get almost halfway there and turn back.
If conducted properly, the flight will be not only legal, but also safety.
