I would love to see London again maybe Bond meet with someone in a bookstore to exchange something, very spy like a drop dead thing.......
Whistle, BC would be nice to see Bond ski on vacation and get recalled to London with no relation to the plot directly
Africa, especially Northern Africa where there is a crisis right now and might be interesting for Bond to go to a country in a war zone, like Chad or Mali?
South Africa should be used since they almost used it for SF?
The Arctic would be a interesting location for a hidden base and could be a interesting chase scene
