   Sounds plausible.

   Imagine a clumpy universe with no gravity.  It has low entropy (lower   
   than the smooth universe).  Now G starts increasing from zero to, say,   
   its current value (at which point the clumpy universe has a higher   
   entropy than the smooth universe).  At some value of G, the clumpy   
   universe must have the same entropy as the smooth universe (which you   
   say has the same entropy with or without gravity).  So for this value of   
   G, the entropy is independent of the clumpiness.   
      
   Someone has made an error somewhere.
