I dont have and copper colored powder coat, but I tested the crome
"looking" powder quite some time ago to see if it infact was
conductive, had to really scratch the surface to get a reading. Infact
I probably was actually reading the base metal. It does have alot of
al in it to give it a chrome appearance, but there is so much more
plastic in it to bond it together.

One thing I thought of allong those line was similar to what you
mentioned.. But instead of powder was to iron gold leafing over the
toner. The leaf will only stick to the toner. 

Then drill out at least one of the holes in each trace throw something
like a header pin in each hole, wire wrap them together and then dump
the whole thing in a copper plating solution.

But........  That seem like alot more work than the old fashion toner
methods and Im not to sure the tonner would keep all to the board
