Interesting, BB could be be more specific on what part of Goldeneye shows that Bond has been out of a job since LTK? I've seen the film several times and didn't ever catch that
The original plan was for Warhead to be set in 1993.
As for using Detonator 2 at all, I doubt it. Brosnan does not even remotely resemble bond in that film, Mostly due to the long hair and stash.
