   No it can't, not without an additional pressure component - at which   
   point it ceases to be a velocity microphone.

   The polar pattern of a cardioid microphone is indeed made up of a   
   velocity and a pressure response but a "velocity" (Fig-8) microphone has   
   only the velocity component and a "pressure" (Omnidirectional)   
   microphone has only a pressure component.  If you buy a microphone that   
   is advertised as a "velocity" microphone, you expect to get one with a   
   Fig-8 pattern..
