Perhaps you could make the traces, and then electroplate a better
conductor (copper, etc.) to make more robust and more conductive
traces.  Of course, you'd have to have connectivity to all traces to
do so.

Or maybe there's a catalytic chemical process to deposit a thicker
layer of a metal wherever the silver is?  Kind of like a 'super'
Tinnit?  That would be a pretty nifty way to make a board.
