well, depending on how creative you want to be......
cheap/easy- you could just fill the shifter whole of the stock console with fiberglass or bondo or something and sand it smooth. then either paint it, cover it with vinyl, or even put automotive carpet over it.
adding an aftermarket console would also be easy, but it will still require some custom work to get it to fit nicely. also, you're still going to have to find a way to cover up the sides where the front of the original console would have slide all the way up (like below the climate control)
making a custom console would be the most rewarding. it would be truely unique and you could make it to whatever specifications you want. putting a dvd player or tv or something would be nice, but that goes back to how much money you want to put into this project.
