You've completely missed the point, the Nurburgring isn't just a normal track but longer it's narrow, long, bumpy, lots of off camber and huge elevation changes, none of that list applies to any Kyoto combo, that circuit would be nice but it would not be anything like the 'ring.
It's hard to explain but if you look at a circuit like Kyoto/Suzuka you can tell that it's been designed by someone whose sat down, its been made with plenty of overtaking good spectating and TV with corners that are smooth and lightly banked that will please modern racing teams who want everything to be predictable. The 'ring on the other hand (despite being purpose built I know) feels like its just always been there safety and raceability not really being connsidered. Making a track feel natural would be very hard the best possibility for an unlicensed track would be basing it on public roads.
