I Say it would be hard but you could do it if you had the money to burn. Like, if you have so much money that buying the wrong car and trying to weld it into a completely different car, and the notion of any other method (all of which are easier and cheaper, except for the method that involves building your own car from a cube of aluminum) is frankly offensive. No, if you are an opulent man and demand opulent methods of vehicle production, then I say go for it
