Well I sure hope so, but I think that every time you ask questions like that it is more hopeful than anything. That is not to say that it cannot be done though.
I think it's just hopeful as well to be honest, but then again, I guess if there is enough interest and enough people ask then Rockstar might look into it one day in the future. It wouldn't take that much time and effort but they will have to make sure that it will be worth them doing it, from a financial point of view.
They aren't going to go to the trouble of doing it, no matter how many people asked, if they would end up losing money. Rockstar are one of the best game developers around and have been for some time, but in the end they are still a business and have to make a profit and that's what it will come down to.
