I can invent such a scenario (but not in pure special relativity); I just didn't know what scenario you were considering. For instance, both twins could circumnavigate a closed universe, with opposite velocities relative to a cosmological observer. In that case, their aging would be symmetric.
So in this case, if on some near pass one twin accelerates and joins the other, we find that the twins are [almost exactly] the same age?
