Well, in sports it could be accepted. German Football Association exists since 1900 and is a FIFA member since 1904. It was the same Association before WW2, for West Germany during the partition, and after 1991. Therefore they are the ones that organised both 1974 and 2006 World Cup and the 1988 Euro. Plus the official name of West Germany is Federal Republic of Germany which is the same as now.
Great idea anyway, an update would definitely be great!
Thanks!
