The Disco II incorporated all the required tech into a solid platform,and it could be translated into heavier chassis quite easily, and clothed in something resembling the current vehicle to produce a pretty neat vehicle.
Whether or not Land Rover could sell something like that and make money on it is the big question.
Looking at the photoshop images below, I quite like the LWB DC100 in picture 4, but to me the back end looks rather short and ruins the proportions some.
