A portable AC that vents out a window will draw HOT air in from outside. I had a portable when our central quit in the stick and brick, and while it did blow out cool air it did not work very well at all. A floor fan to circulate the air helped but I was real happy to get a new central unit.
I don't think anything you do is going to make a big difference in very hot weather. Remember you are in a big aluminum box.
Get the dual hose unit. The single hose pulls air from the inside. The dual hose units pull air from outside then vent the same air back outside.
