Ouch... If it wasn't for the fact that I'm in Australia I'd offer to make you a stencil (laser cut 50 um thick steel foil) and send a few fine gauge syringe needles as well. The latter might raise some interesting questions at customs though.
Given the size of 0402 pads, maybe a better way would be to just punch a round hole in the stencil (~0.5-0.7 mm dia)? Since the solder will spread out anyway when you heat it all up the shape doesn't have to be perfect.
