By "plus .hpp", do you mean "append .hpp to the filename" or "standard header 
names and the standard header names with .hpp appended"? I think I would like 
to see:
  
In boost/tr: functional.hpp, tuple.hpp, etc. 

in boost/tr/std: functional, tuple, etc. as specified in the TR. Each of these 
files might look like this <functional> header:

#ifndef BOOST_TR_USE_STD_NAMESPACE
#  define BOOST_TR_USE_STD_NAMESPACE
#endif

#include <boost/tr/functional.hpp>
#include_next <functional>

Needs some testing, but in theory this would let the Boost TR be a drop-in TR1 
component for any standard library as long as the compiler supports 
#include_next.
