Essexmame, Don't do it, you won't be happy with the controls or anything. Much better to make your own control box, The joysticks and buttons that come on those Pandora boxes are often the cheapest that you can get. Knocking up a 60cm x 20cm box shouldn't take too long to build, throw a pair of printed slagcoin joystick/Button templates on there and drill the holes. Bingo. I bet it could be done in an afternoon.
Although if you are just going to use the box and put your own joysticks etc in there then to save box building time you could go for it. (In which case it doesn't really matter what box you pick)
