Maybe I'm reading it wrong but the Monk of the Four Winds alternate class feature from the APG has an ability that allows you to make three standard actions that can be used to make a melee attack action.
Since Vital Strikes RAW use an attack action I'm assuming you could make 3 Vital Stikes.
I'm not sure of the numbers but it seems you could get a good amount of damage from that. Ofcourse thats at the cost of 6 ki points.
