HELLS YA! i would personally love to see a remake of this game. the one downfall of the original is that it isn't so visually stunning, something which could easily and vastly be improved in this day and age (as shown by the tech demo).
however, saying this i wouldn't be too disappointed if it didn't get remade. and then you have to ask yourself where the line will be drawn. if a remake of 7 is produced, would people want a remake of 8? ( i know i would), then 9, and 10, and next we'l be wanting a remake of the remake of ff7!!! will we ever truly be satisfied
