No, to the best of my knowledge there are no estimators for
bias-approximations available for this case, although there
are some theoretical results in this direction.

I guess you are referring to the instruments for the IV-GMM estimators
used to initialize the procedure. The answer is again no, I'm afraid.
It is in the agenda, however.
