Well actually nothing new. just a pigment_pattern texture with layered 
texture in the texture_map
I figured it was impossible but yes we can !
just texture_patterns   are forbidden in layer textures

see example below

#declare T_spruce =
   texture // wood veins
   {
      pigment
      {
         marble
         color_map
         {
            [ 0.0     rgb <1, 0.5, 0.1> ]
            [ 1.0     rgb <0.3, 0.1, 0.02> ]
         }

        scale 0.01
      }
   }

   texture // layered bozo fouling the wood
   {
      pigment
      {
         bozo
         color_map
         {
            [ 0.0     rgbft <0.0, 0.0, 0.0, 0.0, 0.0> ]
            [ 1.0     rgbft <0.0, 0.0, 0.0, 0.0, 1.0> ]
         }

      scale <0.1,0.1,1>}

   }

#declare T_Etoiles =
      texture
      {
         pigment
         {
            color rgb <0.3229, 0.3229, 0.3229>
         }
         finish
         {
            ambient 0.0
            specular 0.007167
            irid
            {
               0.95
               thickness 1.0
               turbulence <1.0, 1.0, 1.0>
            }
         }
      }

//The pigment_pattern texture
 #declare T_pattern_rosace =

      texture{
               pigment_pattern
               {
                     cylindrical
                     scale  0.48
               }
               texture_map
               {

                  [2.0/60   T_spruce]
                  [2.0/60   T_Etoiles]
                  [3.5/60   T_Etoiles]
                  [3.5/60   T_spruce]
               }

         }

plane {
  y, 0
  texture {T_pattern_rosace }
}



camera {
  location  <0.0, 2, 0>
  direction 1.5*z

}



light_source {

  color rgb 1
