Ignoring the fact that "Bluebirds" live in North America and the song was written by a citizen of the United States for a US audience for a moment, the "White Cliffs of Dover" technically stretch all the way along the South coast of Britain, as the chalk bed that they are part of incorporates large areas of the Isle of Wight, amongst other places.
This cropped up not too long ago on the telly again when we caught a new episode of the BBC's series "Coast" where they were discussing the South Downs and they are very similar to the cliffs at the tip of Kent indeed. When you look across the Channel at the North coast of Normandy, in particular, you can see why.
I'd suggest, if you do it, that you pick a start and end point as close as possible to Dover without it being blatantly obvious. Most people around the world won't care. Those who do know them intimately will just be glad to have them, so I don't think you'd get any complaints at all.
