Second End Dimension

Let's talk Minecraft lore.  I always think of the world as layers: the Overworld on top, the Nether below it.  The Overworld and Nether are separated by a Void, which houses the End dimension.  This raises a question: what is to be found in the Nether Void?  I think that perhaps Mojang should add a second End dimension, one below the Nether.  This Nether-End would be accessed through portals in Bastion Remnants.  It could have a different color scheme, perhaps purple.  If this dimension has any variant of Endermen, these should also spawn in the Crimson Forest, that way it's like Endermen teleport down from the End above into the Warped Forest, and teleport up from the Nether-End into the Crimson one.  Any ideas for new blocks and mobs in this dimension would be welcome in the comments.  Remember, you won't be able to find any Netherendermen in the Overworld, since it's too high up for them to teleport to.  I think this would add consistency to the Minecraft universe, and also make the game more fun without going too far away from Vanilla style.
