namespace ConsoleApplication
{
     class Program
    {
         static void Main(string[] args)
        {
            string xml = @"<Root>
                              <Tag1>
                                <USA></USA>
                                <UK></UK>
                              </Tag1>
                              <Tag2>
                                <FRA></FRA>
                                <USA></USA>
                              </Tag2>
                            </Root>";

            XDocument doc = XDocument.Parse(xml);

            List<XElement> tags = doc.Descendants().Where(x => x.Name.LocalName.StartsWith("Tag")).ToList();
            List<string> countries = tags.SelectMany(x => x.Elements().Select(y => y.Name.LocalName)).Distinct().OrderBy(x => x).ToList();

            for (int i = 0; i < tags.Count; i++)
            {
                List<XElement> children = countries.Select((x, j) => new XElement(x, "var" + (i + 1).ToString() + ((char)(((byte)'a') + j)).ToString())).ToList();
                tags[i].ReplaceWith(new XElement(tags[i].Name.LocalName, children));

            }
        }
    }
 
}
