Yes it makes it more feasible. But even with superconductors, you still need to build out the long-distance grids. With ceramics, manufacturing that much powerline might be the challenge. With the maximum current density reported for this material, you might need a huge x-sectional area. You still have to worry about batteries. Unless if you place equal numbers of panels separated by 120° meridians for example. And then there is coordination between governments. This is probably where such an initiative might fail.
