You can't retell On Her Majesty's Secret Service, what had been up until Casino Royale (if I'm not mistaken) the longest film in the franchise, in a 10-15 stretch of film.
Unfortunately, this is a plot point that won't be able to be revisited in a Craig film anyway. They have to get away from the personal missions. Craig only has two films left, barring a surprise return for a Bond 26, so it doesn't make if feasible that he would be able to get that kind of story told in his final two films anyway. That's something that his predecessor will hopefully get a crack at, assuming that they don't reboot the entire thing again.
