Excellence, here is a translation (from R’ M. Broyde) I found of part of that teshuvah:
[hearing the] shofar and [waving the] lulav and recite blessings [on these performances]
However, it is obvious that this applies only if her soul yearns to perform mitzvot, notwithstanding the fact that she is not commanded to perform them. However, since it is not with this intent but rather stems from her protest against God and His Torah this is not the act of a mitzvah at all; quite the opposite, [it is] a forbidden act, for she commits heresy, thinking it possible for the laws of the Torah to be changed even in a grave matter.
