You shouldn't need to simulate the op-amp noise in spice, and in fact, I doubt you will get accurate noise numbers from a best-effort model. Your best bet is to calculate the effective noise using the input voltage and current noise specifications of the op-amp (and of what is feeding it), and the gain and bandwidth of your application. This isn't trivial to do but it isn't hard. Developing a model with accurate noise performance would be much more difficult.
