Have Bond kill Mr White "the living daylights" style.
While Mr White is going out of a public building in London, after a secret meeting with Quantum leaders, James Bond , who's hiding in a rooftop across the street, kills him with no remorse.

James Bond looks surprisingly like Nicholas Cage.
ooops lol 
I just posted that image to exemplify the idea. 
My idea of a cool pre title sequence Is If bond is about to sniper him when someone else (a beautiful Blonde woman) winds up killing him.
I think it would be cool 
I like that idea. I was up for the sniper bit but then you topped it with this.
Mind you ... it would have to lead on to a decent story from accomplished writers, not Wallace and Gromit, sorry ... I meant Purvis and Wade.
I could accept this if it led to a good tale but I must admit that I personally always have a hankering for a PTS that is a mini-movie in its own right with no connection to the main plot, (i.e. GF, TB, MR, FYEO,) rather than something that is integral to the plot of the main movie, (GE, TWINE, CR).
I like the idea of seeing a snippet of Bond in other adventures where we don't know the full story. It's kind of like in the Fleming books, where he is stuck in Headquarters as the Duty Officer. It shows a moment where he is not rescuing the world from certain doom, he is doing paperwork. In film terms this would equate to him being on lesser missions, days when he is not fighting villains in an underwater/hollowed out volcano /space station, lair.
Instead, he is going after minor villains, probably to execute them, (have you ever seen Bond arrest anyone?) ... big shootout, mad chase, pigeons are frightened, Bond crashing into a garden where a young Swedish girl is sunbathing in the nude. Ah, they don't make 'em like that any more.
In these PTS's, it should not be 'major, saving the world' kind of action, all the time. It should show that sometimes he does lesser jobs, that in their own way, are important but not saving the world kind of important. By that I mean GF type PTS.
But that's just my twopenn'orth.
