on non drive side crank, try rotating it to one of the other 3 positions on the BB spindle.
Is it square taper? ISIS seems more likely.
Which way is the play? Is at a degree of rotation relative to the spindle or some axial movement at the pedal end, or a mixture of thee two? Not that I have any answers, beyond "buy new cranks and BB", but neither does anybody else without knowing what is moving and it which direction.
