That would just be too much fabrication, now if you wanted to put the maverick on some type of mustang frame and rase the car about 4 inches, then i could see this happening, its going to be close for someone who wants to try it, but not me, im scared
you could just take it off. thats the easy part. you still have the post for the door and roof. the roof post is very important to the strength of the car. to remove that you will need to do some chassie stiffening to compensate. also removing the frame around the door window will leave about an inch gap around the glass. you would have to have a custom door glass made that is able to take up that gap.
