hahaha i wish i could do a tiny stencil, but thats no possible same as doing tiny decals. The waterslide are your best option. I have a little experience with those as i did some for the bikerscout helmet. But they guy i had doing them couldnt get the grey correct and i eventually gave up on them. There is white waterslide decal paper you can used, ony thing is youd have to cut them right to the design with an x-acto, but that may work the best if what you have doesnt work out.
