Here is another possibility
LAX-HKG-DEL-NRT-SIN-NRT-PER-SYD-MEL-LHR-IST-BUD-HEL-FCO-ORD-SJU-LAX
52565 BIS miles.
The must do's conflict a bit with the goal of maximizing miles. Maybe you should consider doing some of them via cheap economy tickets (SYD-MEL $70 return) especially the ones in Europe and using the extra segment for longer travel. LHR-MCT comes to mind.
