Ah, the old external tank proposals. Didn't use of them in orbit turn out to be impractical? Basically, they were never designed to last in that environment and the argument that "with little additional cost" they could be modified wasn't anywhere near the truth.
No one knows given that we never actually put external tanks into orbit.
