Craftable gateway blocks

I have an idea for an end game long distance travel system:
You go to the end and right click on an end gateway with a blaze rod, This would result in a gateway covered rod [It wouldn't destroy the gateway] placing 8 of them in a crafting table makes two gateway blocks which are linked to eachother, the blocks would teleport any entity exactly like a normal end gateway block would, just with an exact position instead of scattering the entity around. it would also load the chunk the other block is in for 1 or 2 ticks and to avoid lag machines every entity would be limited to 1 teleportation every 5 seconds or so.

What do you think?
