This is one ancient wonder that it would be great to see rebuilt. It would be a great tourist attraction. It has been proposed over the years but unfortunately, the Greeks being the Greeks are too disorganized and debt-ridden to get it off the ground.
About ten years ago an architect was promoting his plan to build a much bigger tribute to the Colossus, with an interior space for a museum and other amenities.
It was far too ambitious. Just to build it might require reclamation of some seabed in order to support the construction infrastructure, and perhaps as its building side.
Oh, and a giant pile of money.
Rhodes is also close to the coast of Turkey, so any tourism would probably come from there and/or mostly benefit the Turkish mainland. I think there are a couple of topics in the above list.
