People have been coating silver on glass for many years, so I cannot see 
why copper cannot be deposited, even if over a silver seed layer. Even 
if you could economically drill holes in glass, I think thermal stress 
cracking of the soldering process will haunt you. Talk to people who 
manufacture hybrid PCBs and use those 800C oven cured conductive inks. 
Shouldn't be difficult to set up in one's own backyard.
Have fun.
