It would certainly be a lot safer to use hand tools. After working with aluminum and stainless for a long time, copper would be a dream to work on, for me. Believe me, it won't be _that_ much work with hand tools...copper is very soft compared with other materials.
Remember that removing deep scratches will result in a depression to some degree or another, unless you thickness the whole plate to the depth of the scratch. If that's a problem for making prints you might be out of luck.
