Looking at the plates for the vor 29 and 11 the inbound tracks are displaced along way from the rwy centreline. This would not be ideal in weather below the minima.
Perhaps the rwy 04 approach would have been worth a shot. Although its shorter, the rwy is lit and the inbound track is only 2 degrees off meaning the threshold at least would have been straight ahead. I'm sure 4700ft would have been long enough for a very light Westwind in the wet.
Maybe that approach was not available at that time.
