I got it... scaling the checker pattern and then reciprocally rescaling 
the textures does the trick!

plane
{
   y, 0
   texture
   {
     scale x*1.5
     pigment
     {
       checker
       pigment { P_Flag_Palau scale 0.3 scale <2/3, 0, 0> translate 
<0.42, 0, 0.5> warp { repeat x } warp { repeat z } }
       pigment { P_Flag_TrinidadAndTobago scale <2/3, 0, 0> translate 
x*0.65 warp { repeat x } warp { repeat z } }
     }
     finish { ambient 1 diffuse 0 }
   }
}

See you in Khyberspace!
