I don't see any problems fitting this with -gllamm-. You treat choices
as fixed, then alpha_j is a part of the fixed effects, and gamma_j is
the choice-specific coefficient (loading). But, in all likelihood, you
don't observe utilities, so in the end it will boil down to some sort
of -mlogit- link. You need to describe the model more fully.
