No - because you started out with a tirade about why it was impossible,
instead of simply asking why I might be considering this conjecture:

RSA Key run lengths:

  1  2  3  4  5  6  7  8
 -- -- -- -- -- -- -- --
 10  9  3  4  2  0  0  0        0x67b9e0ec4f20d95e;    //DES Test
  9  6  2  2  1  0  0  0        0x43d26dd827;          //RC5-40 Test
 10  4  3  2  1  0  0  1        0x510678042628;        //RC5-48 Test
 20 12  4  0  0  0  0  0        0xda989a5ab31114;      //RC5-56 Test
  7  9  5  1  4  0  0  0        0xf918c79c9f1be582;    //RC5-64 Test
 13 10  2  3  1  1  0  0        0x3d986e6bf1be4bda;    //DES Challenge
 15 10  3  3  0  0  0  0        0x9909C24C742B53;      //RC5-56 Challenge
 13  7  5  3  2  0  0  0        0x39D0F454C17DDE63;    //RC5-64 Challenge
 -- -- -- -- -- -- -- --
 97 67 27 18 11  1  0  1


Which for 453 or so bits, is biased, but not horribly so.
