There's actually about 2 years of Gray Fox as a ninja that could be filled in. Naomi helped him escape and kill Clark in 2003, Shadow Moses was in 2005. You could easily start the game with him killing Clark, escaping the Patriot facility he was held in, and going on the run until Naomi helps him fake his death.
