Neat solution. It looks more at home than some odd shaped ones being sold as “ genuine parts” !
A few years ago I called in at Life’s whilst en route to Morgans at Windermere. It was to see a roadster they were selling. It had a coach built rear compartment that followed the lines of the rear of the car and was designed to hold a wheelchair. It did not detract from the normal lines of the car, was removable and with minimal modification would have been a proper boot. It was sold when I checked soon afterwards. I was tempted.
