Put the End above the Overworld

This idea would place the End dimension 2,048 blocks above the overworld, and redo the Void slightly. The Void would, in this idea, be an analog of space, and deal damage through freezing and drowning (asphyxiation). This fall would be survivable  using methods like Respiration 5, or leather items. The void would still destroy items and non-mob entities, but would allow a fall from the End isles to be survivable.The reason why I suggest this idea is in an effort to follow one of mojang's tenets of "Do not let hours of player's work be destroyed by the ambient world." With this in mind, I ask you to please consider this suggestion.
