silver, copper and fixer deposits

Hello all,

Is is possible to use copper scraps to plate out silver from spent fixer?

There seems to be a mild attack on the copper if it is placed into spent fixer.
I am almost tempted to try copper plate etching for intaglio printing plates
using the fixer as a mordent.

I am have held off due to the potential of other by-products... my knowledge
of chemistry is really rusty.

Is there anyone on the list with chemistry hints, or a resource book that can
steer me in the right direction. I thank you in advance.
