Well, there's always Enterprise. Or has it been scrounged for spare
parts so much that there's nothing left?

Rebuilding to flight ready would be at least as costly as building a
entire new orbiter.

plus from what people here have said it would be to heavy. The first three
had a heavier wing structure that was redesigned to be lighter and stronger
due to data from Columbia's first few flights. That was one reason for
Columbia to do science. To heavy for lugging stuff to ISS. So, I would
think even if it were not so costly or intensive, it would not be a gain
for doing ISS support flights.
