The Grand Prix of Europe (rotating between one off races in UK, Germany, Spain, France and Italy)
Killing off F1 in its traditional heartlands for the sake of an idealistic notion of taking it to places with no motorsport history is certainly popular with Mr Ecclestone, but fans should not rush to support the idea.
Imposing F1 top-down on a country with no tradition for the sport gives us the kind of scenario that we've seen - of empty grandstands and after the initial government (taxpayer) money runs out, eventual failure and retreat. Most of the countries you list there are at the very core of F1 history. We've already lost France, and you would also sacrifice UK, Germany and Italy, where there are passionate and knowledgeable fans who will actually attend and make the race commercially viable, not to mention giving the drivers the live audience they deserve.
State-subsidised races please Ecclestone, who can rake in easy money from the taxpayers of the countries where governments bid to be an F1 host for their own prestige, but I don't believe this is in the real interests of either the sport, or the people in the countries concerned.
