Not exactly. First, the most common way to "arc" the shoes is by grinding them with an artificial center. The shoes get thin spots like other grinding methods MAY do so no gain AT BEST on the wear factor.
Second, over the decades many shops have altered the radius of the steel shoe by peening the web. These will not easily grind to your proper arc AND you have now changed the length of the shoe between it's two anchor/alignment points. Also it means it will have to push outward at a different rate than it's counterpart unless they're an exact match.
