There have been devices sold that combined two 120V 15A cords to drive a 240V receptacle which require both 120V circuits to be live and of opposite polarity before closing a relay that energizes the receptacle.
Trying to do this with fixed (even if temporary) wiring instead would run afoul of the need to use a two pole breaker at the source panel.
To avoid GFCI problems you would certainly have to drive the two 120V circuits from a two-pole GFCI breaker.
