I like the idea of the flip-flop but as you say it will be over or under-exposed depending on when the slave flashes, however why not leave the flip-flop in place and dial in a couple of stops of flash compensation ? Alternatively put the camera into manual mode and then adjust the slave flash output for the shutter aperture. Of course your particular model may not have this feature but it may be worth checking the user manual or the menus.
