Switzerland, no. You would have a point with Italy and Burgundy - just that there is no independant Burgundy anymore, of course. The kingdoms of Burgundy and Italy were what remained of the Central Frankiish Kingdom. However, both were also conquered territories, who already had an own dientity BEFORE the Franks took them over, so I wouldnt really see them as sucessor states. France and Germany started, as nations, 843 with the Treaty of Verdun, Italy started, as a nation, earlier, with, say, the invasion of the Langobards.
And Lorraine is a sucessor to Lotharingia, but no independant, souvereign one. It descends from the two Lotharingian duchies that ended up in teh East Frankish/German kingdom, so, yeah, does not count because not independant anymore ever since, as said, Treaty of Merseen 870.
