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?

Somewhat unrelated, but window awnings are an often overlooked solution for your exact problem. They’re not quite as quick and dirty as some reflectix or aluminum foil, though.
