The syringe can be 'fed' with a stepper.  the syringe can be moved 
just like a spindle on the X/Y/Z so it would be an extreemly simple 
matter to move it to a fraction of a mm from the board, and then 
dispense any quantity.

I imagine that a pair of drops on a pad would be as easy as moving to 
the X/Y, then to Z, dispense while retracting slowly.
mmove to next X/Y and repeat.  

This would be very very simple to do both from the dispensing side of 
the machine as well as the X/Y locations.

Since this would be a non-contact device, it could easily be clamped 
on the side of your existing head and by only adding one additional 
stepper for dispensing, you would have a complete unit.

Of course, my question is where to get low cost solder paste ?
