That'd be great. If it's not too much to ask, please send me the archive. By the way, in meantime, I took a look at getfem_models.cc. Making your own brick seems easier than I though. I started coding my own version of basic_nonlinear_brick that works for many multiple scalar variables. If I'm successful, I can share my results later.
