im no HVAC expert but....if it were me, I would likely plumb in a secondary/auxiliary return in the basement, with a damper to switch between the main return in the living space, and the return in the basement...
with the return in the basement, it would pull the cold air out of the basement, and push it upstairs, and with the basement door open it would draw the tempered air back to the basement
but that's just me...
