Minivan/Truck Convertible

Have you ever thought of making a minivan/truck together? I mean a minivan that can carry about 7-8 people that with a flick of a switch can turn into a truck to carry heavy and big stuff. It would be good on gas and easy to afford of course. The minivan part would have mechanical seats that fold down flat so long, tall, heavy things can fit. It would still be able to fit about 5 people when converted to truck. It would be able to do all that with one flick of a switch.I am submitting my idea to you because if you decide to design a minivan/truck, I would like to be the one to test drive it first.Thank you for your time.
