There is absolutely no way that "rock" prison will "reopen." It is hugely deteriorated and makes the federal park service a lot of money as a tourist attraction (aka: trap).
It would make more sense to "reopen" Fort Point (used to be a prison too) located directly under the Golden Gate Bridge. Fort Point is on the Presidio (Fed property) at Crissy Field. All infrastructure is in place and it would cost far less to operate on a daily basis.
