If you look at SHIII's Bismarck, her main model has three materials linked to it: The first material, named 'normal' is used on the hull, and it has a texture with alpha channel embedded and a SpecularMask controller attached. The second material, named 'complete', is mapped on the decks and it has no alpha channel nor SpecularMask controller; the third material, named '2sided', is used on ladders, railings, etc, it uses the same texture as the 'normal' material and likewise it, it has a SpecularMask controller attached but, as the name says, it has the 'Two sided' flag enabled. So, in total, we have two 'specular' materials linked to the same object, and both have the specular map in the alpha channel of their diffuse texture. Other stock units that I have had a glance into, are not dissimilar from the Bismarck.
What you are suggesting, would probably require the usage of the Texture Map chunk in place of (or together with?) the Specualar Mask controller. This chunk, allows additional texture maps to be linked to the diffuse map. Three texture types can be selected: Ambient Occlusion, Specular, and Normal/Bump. In stock game it seems underused, and it is only employed for the mapping of AO maps or normal maps on a few objects. I couldn't find any example of it being used for specular mapping (neither in stock nor in modded files), but we can try
