I would think a Double din under dash setup would sorta defeat the purpose, but thats just my opinion. You could probably make something that would work. Get a double din dash kit that will allow you to use a cage or some mounting system and make something out of fiberglass or similar material. Not sure what you drive but a double din might stick down pretty far below the dash, might hit your knees on it or something.
This is the setup I made for my truck, used a single dish dash kit mostly just to get the opening and then all fiberglass.
