It's a simple image and I am not averse to changing the image in favor of something else, perhaps a more solid image for the map portion, perhaps another image entirely without being a map at all. If we can come up with samples and share on the mailing list - maybe that would be a good way to explore this?
I also think a sub-project has merit.
I don't understand when you say the "template practically ignores Sicily, barely showing an outline" -- It's not ignoring Sicily by any means, though the red/white pattern on that portion leaves half of Sicily red, half white with an outline, as it does with other parts of the map.
The template is more than the image -- which can be changed -- it brings in the Italian Roots category, and now with the new convention one can also include other items like "needs sources" ...
