I am not sure how to specify datum's for a turned part with a hexagon cross section and different size internal counter bores. Most of myexperiance is on turned parts were made out of round bars

Are you saying you want the c'bores to be concentric to the hexagon? Maybe you can make a datum from the centerplane of each of the flat pairs, then add a symmetry tolerance to all three flats datums.
