JFK-LHR-HKG-NRT-LAX-BOS, then later BOS-SFO-JFK. Buy a BOS-NYC as a seperate ticket. You have a second (almost free) trip and get around the 10 days minimum.
No you can't. Other than transcon restriction, following rule porhibits this itinerary.
Travel on the last international sector must commerce no earlier than 10 days after commencement of the first international sector.
