I once had an idea for a James Bond story focused on a slightly different end to On Her Majesty's Secret Service.
Instead of being shot Tracy Bond is "killed" at the wedding when a small bomb, planted by spectre, goes off. Bond then recieves a phone call from Blofeld, so we know who was behind the deed. Something like "Did you like your wedding present, Mr. Bond?" But not as cheesy. Years later, there seems to be a series of murders, of people close to Bond, it appears that someone has a vendetta against him, Bond of course, believes that person to be the new head of SPECTRE, bent on avenging Blofeld's death. When he finds this person, it is revealed that in fact, he is not the man behind the war at all. Someone else is pulling the strings, slowly, a wheelchair is wheeled into the room. "Remember me, Jame?" Tracy had spent years in a hospital, though her husband had thought her dead, she had been saved somehow, and finally, she snapped when she heard of her husbands affairs, and in consequence decides to destroy him.
so instead of a female James Bond, we see Tracy Bond as a villain. She has the connections, the knowledge of Bond's life, and the motive to do so, if she somehow survives OHMS without Bond's knowledge.
