As others have said - you can make a ski boat into a decent wakeboard or surf boat, but you can't make a wakeboard/surf boat into a ski boat. So you need to decide what is most important. If you want to really enjoy skiing, buy a ski boat and you won't regret it. In your list I see three that are boats most here would actually ski behind: Malibu Sunsetter, Malibu Response, and a Nautique 200 (although it has been noted this model did not start until 2010). I've skied behind a iRide and a Wakesetter and well, I can say I did it, but I'm glad that I have a real ski boat.
My encouragement based on what you have written is to buy a water ski boat and avoid the wake boat hulls.
