Over on RC Groups a guy built a stand-off scale model of a JU-52, the German Tri-motor from the 30's with the corrugated skin. He used an inkjet printer and printed the corrugations on his covering - it actually looked pretty good. I bet you could do the same thing for your drywall stacks. You're already printing the ends, just print the sides too. Then you could just wrap that around your block in one or two pieces, hiding the wood grain. That might even be easier than putting a separate piece on each end.

Edit: Actually, you could do something like that to make most of wrapped loads that you see on the road these days. Just did a little back of the napkin figuring. You wouldn't be able to print a 48"x96"x36" load at 1/14 scale in one piece on a letter sized printer, that's 8.5"x11". If your printer could handle 11"x17" you could do it, you could even do scale 12' sheets on an 11"x17" printer.
