vehicle wrap of a 3d xray of a 2002 nissan pathfinder

so we are getting into vehicle wraps and want something wild. My idea was something along the lines of and metal shell with kinda X-ray image of the rest of the vehicle. Sounds really difficult. I would like to output vinyl at 300 dpi But know the file would be big, in the past I use the attached templets that are to spec my creating and I scale them to 2000 percent to get it to full size. Is there anyway you could create this on a 1/20 scale like in the files I have attached. looking for some ideas. I will pay you good. I thought if you had an hour or so to do something up to see if that's the right direction. I know the man when it come to this crazy design, I just what it to look sharp when it's scaled up. My truck is brown but will be full warping it with white printed vinyl. All sides could look different say dog in the back seat maybe. I am not sure if anyone is up for this strange design. tx
