Marco has a good idea, if you like the moonroof look. Or you could install one yourself. Be sure to NOT use any type of saw, though. Nibblers are great or a side grinder, but NOT a saw. Saws stretch the metal when cutting and will warp the crap out of the metal and OMG it will be an awful sight. I customized vans back in the late 80s so I saw my share of home installs. NOT pretty.
Whichever way you go, I wish you the best of luck.
Good luck and have fun.
