That should be valid, but only if the texture is like the following example.

#declare ColorMappedTexture=
  texture {
    pigment {
      granite
      color_map {
        [0 color rgb <1,0.3,0.1> ]
        [1/3 color rgb <0.7,0.5,0.3> ]
        [2/3 color rgb <1,0.7,0.5> ]
        [1 color rgb <0.5,0.3,0.1> ]
      }
    }
/* a finish statement could also be here and can be overriden later */
  }

texture {
    ColorMappedTexture
    finish {specular 0.5 roughness 0.01}
}

If you are still referring to the 'cannot layer over patterned texture'
limitation and your inability to add a finish to change ambient, diffuse,
specular, etc. I think you should be okay until trying to add yet another
texture statement. For example:

texture {
    PreviouslyDeclaredLayeredTexture
    texture {AnotherHere} // error
}

whereas the next example is okay:

texture {
    PreviouslyDeclaredLayeredTexture
    pigment {AnyColorMap} // no error
    finish {AnyFinish} // also no error
}

This being POV-Ray version 3.5 I am using here, not sure about the previous
versions.

My guess is that you are getting textures added into textures, and therein
lies the problem.
