I imagine such a storyline might be difficult. Realistically, if the modern NCIS team got involved with a cold case like that, they'd want to talk to the original team. Can't talk to Gibbs as he's off the grid in Alaska. Can't talk to Franks as he's dead and his ghost is haunting Gibbs. That leaves Randy and Dominguez, but whether they show up or have their absence explained means Origins is stuck to what their fate is.
