Except that the Commandante cannot be The End due to age differences, The End was already over a 100 when he died in 1964 during Snake Eater, Chico was born in 1962 (as he was 12 by the time of Peacewalker set in 1974) making the thought of The End being in that picture with a young Chico impossible.

One could argue the whole Grandfather thing but let's face it, he's only considered to be related to Chico because of that ridiculous joke theory of Chico being Quiet.
