I don't think there is a problem if you use another
metal, or even a non-metallic support for the silver
layer. Actually Theiss provides daguerreotype plates on
brass I believe, and people have made dags on silvered glass
(silver deposited via vacuum deposition - no polishing needed).
The main problem is to find a metal on which the silver
plating adheres well.

Normally, only one side of the support is silver plated
(to lower costs), but if you plate both sides sure you
could engrave the back by scratching the silver layer.
People sometimes 'write' on the back of the dag plate
(the copper surface) using a point.

Nothing to worry about oxydation, which is prevented
by sealing the daguerreotype under glass, preventing
oxygen from the air to oxydize the silver on the dag

Hope this helps,
