I would use a underside pre-heat unit and a hot air pencil. Removal, flux pen with a no-clean flux (if possible) and replacement time could be as quick as one minute depending on substrate composition, solder alloy and operator skill. Use caution to not overheat or ramp up the temperature on the device too quickly so as not to damage the device.
