I think that while your analisys is correct, you're a bit too much optimistic, 
because you forgot something. ;-)
To keep a long story short, I think this works perfectly for icons >32x32, but 
for smaller sizes details have to be removed and strokes thikened, so when 
rendering the svgs at its multiples you end up with way too thick borders and 
incorrect icons. :\

yup, that'd rock! :-)
