Am I going to reduce a room’s temperature covering a huge hopper window with either paper or reflective aluminum foil, but leaving the window a bit open when the sun shines directly into the window?

Yes, covering the window will reduce solar heating by a lot, even if you just use basic blinds or curtains. You can also get stick-on window film for cheap that might work better than blinds. You could also use a low-profile fan like this one to get airflow without exposing much of the window to sunlight.
