sggraham,
Not sure what would be done in Holland but you will need to reverse the usual building process (because you are building the inner wall last) so the section through your modified wall would be outer brick, cavity with ties, breathable membrane, studding incorporating insulation, plasterboard. Somehow you must make provision for any condensation to go outwards (not inwards) and effective sealing of the perimeter of the inner wall - these will be dictated by the existing floor/ceiling.
Putting battens direct on the wall as you suggest will lead to horrendous damp problems and the lower wall will be wet and rotting in a short time.
