Not really. The overlays are handled special. It's not just a fixed
integer. The number 16 comes from the four bits you can pass to a image
list object. And the other bits are already used for other stuff, so
increasing the number of overlays isn't possible without breaking the
compatibility. The only way to do that would be if MS would create a
completely new shell extension handler for that, and then draw the icons
with API's they have to create first too.
