Yes, this is a very good idea - however, you need to consider how many _statistically_significant_ points you need too get a proper antenna pattern - and you need to be aware that you can get spurious results from reflections - so ideally you will do the same exercise from several points to try to eliminate the effect of these spurii.
The technique is a form of 'tomography', used not only by antenna engineers when needed but greatly used by remote sensing scientists and medical imaging people.

Just came up with an idea; if you war drive your neighbourhood -and beyond- with GPS enabled, save the map, put up a dish-setup and swipe it across the neighbourhood, you can determine the reach of the dish setup.--
From the map simply calculate the distance of an AP found in the war drive to your dish setup .
Even without hi tech equipment it is then easy to find out what setup works the best for you.
