thats not a bad thought process an alternative 2 seater body style that could convert into a 4 seater!!
Landrover produced a commercial version on the discovery 3 and 4 that had the back seats removed to increase the load space (it also had VAT implications) - all the fittings were still there so if you wanted to add the rear seats to your "commercial" you just needed to find the seats (I am sure their were some legal implications also)
Perhaps Morgan could use the same concept and have a long wheel based version of the 2 seater that looked just like the current 4 seater and maybe an aftermarket supplier like Uncle Melvin could provide a rear seat kit.
I am sure at one stage side lights were fitted but not wired to comply with regulations so a president has already been set
