I have been intrigued by free floating design, but that means you put up with equal head tensions. On snares, I find the best sound to be when the snares side is around a fourth higher than the batter. It would seem to me that it would make sense that both heads could be made so that when both heads are at equal tension, the snare side would be tuned higher. This could be regulated by snare side head thickness, to develop a certain pitch range at a given tension. Has this been tried?
