Yuk! No! Don't do this! Why produce half-transparent tiles when you could just carry on producing tiles of the neighbouring countries (or even the whole world) in your national style. As a British person who travels to Paraguay, I want to see a map of Paraguay in UK styles (and probably English captions where available). The Mapnik layer currently gives me that. There's no need to take that away when we implement a Paraguay style map. What we need is entire global renderings in different styles. I hate it when I go on holiday and I can't understand the colours of the maps. A choice of UK Style, German Style, USA Style rendering for the whole world would be nice, particularly if it defaulted to whichever country you were in by IP address geolocation. I'm sure it will be easier to impliment than a single map with inconsistent syle, and I'm fairly confident that the resources required are not huge - particulary as introducing new layer servers reduces the load on the existing single tile server.
