Not much point mounting a chuck. The rigidity issue is the MT2 arbor, so you may as well mount the workpiece directly on a MT2 arbor and take light cuts. You could mill the pulley conventionally, within say 20 thou over size, then finish it mounted in the spindle.
Just some thoughts

I suppose I could try drilling and tapping the tang though... |
