I suppose you mean standard deviation of the error term rather than standard error of the error term. The problem with such heterogeneous choice models is that they tend to be hopelessly sensitive to getting the functional form of _every_ part of your model correct. Any deviation in the probability part of the model influences the residuals, and the model for the residuals influence the parameter estimates in the main probability part of the model. So any error in your model tends to propagate to all other parts of your model. So I do not think that that is a very promising avenue to pursue.
