Only because you can use thicker cables and only for very long distances. You are failing to account for all the losses, specifically boosting and bucking to the high voltage. This is also apparently only worth implementing for transmission distances of more than a thousand miles, which is unnecessary to do since generating stations are much closer than that to their loads. And one must also bury these cables since they are so heavy the towers cannot support the weight. Does not sound feasible to me.
