It should be doable. One question is how to resolve conflicting members 
of the two structs, which can be defaulted to one of the policies "cause 
compilation error", "do name mangle", "ignore second", etc.

I pass local variables to getopt and then construct a struct from them:

   int a;
   double d;

   getopt(/* ... */, &a, /* ... */, &d);

   myFunction(MyStruct(a, d));

Do you want to pass members of a struct to getopt?

   auto m = MyStruct();

   getopt(/* ... */, &m.a, /* ... */, &m.d);
