Ahhh I tried it for a while however even with 3*CX + 2*QF + 1*VS direct to Syd each day it was very difficult. I rarely saw my family, The time change between Syd and Hkg is 3 hrs I'm not sure about LA/Hkg? My advice would be to plan on living in Honkgka's! Hell you might even enjoy it after a while!
