Lou - In my book, that looks like a trace with a cross section somewhere around .025 square inches. While it may be possible to design such a beast, I would be very concerned whether one could successfully load and solder the board without destroying it in the process. I have, in the past, had fairly good success with some of the laminated bus bars offered by several of the specialty shops. These can be had for either solder-on or bolt-on applications. Custom designs are relatively inexpensive.
