What we wanted (though we did not need it) was a model structure similar to the Joyal-Terney but in dimension 2, and of course it would be different from this one. I am sure too

In Section 7 of Bunge-Hermida we actually discuss Lack's model structure on 2-Cat(S). We did this only to show that it is not suitable to get 2-stack completions, in case someone would think of this idea. The (ELP) is too restrictive for that. This may have led to your misunderstanding when we actually agree.
