that won't work out for you, man. trust me. anytime i'm actively trying to get a VDB, it never happens.
on the plus side, there are worse airports than LAX to be 'stuck' at for a few hours if you have nothing else to do that day. walk to in-n-out, uber to manhattan beach and hit the bars there. if you have access to the *A lounge in TBIT, catch a buzz there before your TPAC.
