Is there any way I can gain access on i inside B?

Not directly, but as you ask for /any/ way -- yes:

   struct B
   {
     void foo() { outer.i ~= 1; }
     ref A outer() inout @property { return 
*cast(A*)(cast(void*)&this-A.b.offsetof); }
   }

Note this will work only as long as you have just one B
instance in A and B is never created or copied outside of A.

OK. I have en entire graph, whose nodes are Bs inside A. So that 
might not be totally appropriate for me. Thanks anyway, I always 
forget about offsetof
