Hi Rob ... If I understand what you mean, I ~think~ it's possible, but I've not gotten that far along yet. The differences would generally be quite subtle, but, with a film like Tech Pan, which is more orthochromatic, or the infrared films, it should be easier. I started working with an infrared "profile" (for lack of better terminology), but I'm not quite happy with it yet. Still, it ain't too bad.
Perhaps if you were to look up the spectral response of a particular film, you could adjust the Channel Mixer layer to more closely represent the response of that film. Maybe adding a little more red and reducing the blue somewhat might get you a little closer to Tech Pan.
