Sharp eyed people may notice a "Replace SHP Image" option in the right click menu that has functionality that lets you select images to replace an existing SHP icon with.

You can then set the replacement SHP image's header with SHOW SHP HEADER DATA.

What's remaining to do is the last major hurdle -- trying to figure out how to get this thing to do correct SHP compression and then reassembly so that the Replace SHP Image is actually useful, and not just a tech demo.
