Come to think of it, I could see Lazenby doing this but it has to have a follow up feel to OHMSS which SOLO simply doesn't have or ever will. I like the idea of having Blofeld in the story, but it would have to drastically change to be more akin to YOLT the novel.
M sends Bond on a diplomatic mission to Africa to lend aid in a civil dispute between two warring African tribes who are being manipulated by Dr. Shatterhand who's sending his assassin Breed to kill chosen targets on both sides. Blessing Ogilvy-Grant sells out Bond to Shatterhand and Breed is sent to assassinate him. Believing Bond is dead the operation in Africa is a disaster and civil war ensues.
Bond survives and returns to London, files a report to M who in turn gives Bond a fortnight's leave. Unable to put this behind him, Bond begins the search for Breed and Blessing where he travels to Washington D.C where he stumbles into a CIA operation investigating Breed and Grant. When he's ordered not to interfere Bond ignores and makes the CIA operation worse for wear. Bond encounters Blessing, Blessing informs Bond that Shatterhand is really Blofeld and that he's holed up in Japan and Bond shoots her.
Enraged, and knowing that the CIA will report Bond as a rogue operative now; Bond travels under the scope to Japan where he's immediately snatched up by Tiger Tanaka. With Tiger's assistance he and Bond discover Blofeld's location on a guarded island. With the help of the Japanese navy, Bond, Tanaka, and a handful of operatives and commandos assault the island. Tanaka and Breed have a very good battle, while Bond goes directly after Blofeld to where Bond has the fight of his very life, resulting him squeezing the life out of Ernst Stavro Blofeld with his bare hands.
Afterward, as Tanaka and the Japanese navy tidy things up, Bond is betrayed by Tanaka and turned over to British authorities where Bond is taken directly back to M. A philosophical discussion about honor and duty ensues between the two whit M dismissing Bond from his presence, angry at his finest officer. Bond leaves M's office. Kisses Moneypenny for what he believes is the final time, walks out of the office altogether and back onto the elevator.
M watches Bond leave out the building from his window, smoking his pipe and thinking hard over Bond's fate. Deciding to keep him onboard the Double O Section when Tanner enters, holding an EYES ONLY folder.
Make of it what you will, feel free to add to it if you want to. But it would have been a better story than what Boyd had given us.
