Yes, I think I like that idea as well;I'd prefer it ifGood start, Harmsway.Well, I have a treatment I sketched out on my free time, and it starts like this:
SpoilerBond and Madeleine are traveling, the way Bond and Vesper intended to do, and they've essentially gone off the grid for a few months.
The PTS finds them celebrating on the French Riviera when an assassin interrupts their romantic reverie. Bond kills the assassin. Shortly after the encounter, Bond finds that MI6 has frantically been trying to get in touch with him: Blofeld escaped containment in the Falklands, and Bond and Madeleine are now the target of a manhunt thanks to an enormous bounty placed on their heads by Blofeld.
SpoilerI hope if we do have a Bond-v-Blofeld grudge match it doesn't involve the death of Madeleine, because it's too obvious and it's been done before. Your idea of them both having to fight ESB sounds good. Could end with the ultimate wrench - Blofeld defeated but Bond can't leave his former life behind and Madeleine can't live with him because of it.SpoilerBond leaves Madeleine, knowing she'll never be safe with him, and goes off to end things once and for all (perhaps, knowing she'd never leave him willingly, he departs secretly after bringing her to a safe place of some kind).
Perhaps, if it ends with Bond's presumed death, Madeleine greets the news with tears. Meanwhile, Bond awakes on a beach with no memory of his life, finally free of his cursed life.
Spoiler
the only way Bond will escape his way of life and his past is to have no recollection of it. Its the sort of ending I can imagine the current team writing and Sam Mendes directing. The only downside is the "death of Bond" has been done before, within memory of audiences in SF. On the other hand - the ending - cut from a tearful Madeleine to a wood panelled office in Whitehall, Tanner, Moneypenny and Q in attendance, and M at his desk reviewing an obituary, and an earlier one involving a mission gone wrong in Istanbul years before. With a sense of grim finality he says "You only die twice."
