Four shuttles are
required to maintain the shuttle program and to support the ISS. And part of the reason why we got a new shuttle so soon after Challenger was because NASA kept a large store of spare parts that were used in assembling Endeavour.
That store has never been replenished.
We would basically have to build a new assembly line to replace Columbia, and what would be the point of doing that with 70s technology?
It would be better to arrange to send the money currently in the shuttle program to the Russians in exchange for them building and launching enough Soyuzs to keep the ISS running. Considering what the Russians can do with funds we'd consider paltry, that should be more than enough.
In the meantime, we can appropriate new funding for a nuclear rocket mission to Mars, which will be the new object of our manned space program.
