That should work. In CSS there are media specific styles:

   @media print {
     body {
        color: black;
        background-color: white;
     }
     h1 {
        font-size: 14pt;
     }
   }

This could be adapted to

   @background aerial-imagery {
     way {
         casing-width: 0.6;
     }
     ...
   }

But I'd suggest we keep the syntax simple for now and introduce this 
feature in a later version of MapCSS...
