I've been wondering, does anyone think an alchemist of high ability could make aetherium, or aetherium substitute from samples of the real thing?

On a side note, I understand great quantities of aetherium were originally dug up by the Dwemer and was stored at Mzulft. Strange that it should all seemingly disappear into thin air, that is unless it was hidden, just like the forge was. Anyone think there's a possibility that it could still be there, hidden and waiting to be discovered?
