projection and regular textures?

Can I have multiple layers of projection painting or would I be able to say wrap a normal map and also projection paint another layer. To try and explain it better. Could I uv unwrap a object and add a normal,displacement,specular, etc… and then use the projection painting for the color texture. What would realy be nice is if I could some how add the projection painting to the displacement and use as a alpha.

anybody out there in blender land?

I think that people may not know what it is you are trying to do, or why. I see that you’ve explained it, but I’m really good with textures, and I have no idea why you’d want to do that. If you use different methods for your normal and color maps, the normal map won’t have any relation to the color (diffuse) map.
