Ok perhaps they didnt come from the caves, but, heres a quote from LOTR to debunk Gate-chokepoint part:

"Down from the hills on either side of the Morannon poured Orcs innumerable. The men of the West were trapped, and soon, all about the grey mounds where they stood, forces ten times and more than ten times their match would ring them in a sea of enemies. Sauron had taken the proffered bait in jaws of steel."

Your idea about Aragorn using the Black Gate of a choke-point does not hold up from this information does it? I considered it myself, until I remembered this part of the book.
