Having both fans blowing outwards will initially exhaust hot air if it's near the top of the room, but that air will need to be replaced, likely from via the condo door or other source, which can also be hot. So not recommended.
Having one fan blow out and another blow in would create a draft, but it will also move the AC air to one bedroom and exhaust it, while replacing it with hot air from the other bedroom, also won't work.
Your best best is to put both fans in the doorway of each bedroom, drawing the cold air in from the floor of the living room and into the bedrooms. You don't remove any air from the apartment or draw in new air which will increase the duty cycle of the AC.
