Additionally, even if you did want to recreate a Saturn V, the designs themselves aren't going to get you very far. Most of the tooling has been lost likely along with much of the institutional know how, especially on the technician side of things. I'd be very surprised if you could recreate a functioning Saturn V for a lower cost than designing an entirely new launch system.
> As part of the Space Launch System (SLS) program, NASA had been running the Advanced Booster Competition, which was scheduled to end with the selection of a winning booster configuration in 2015. In 2012, Pratt & Whitney Rocketdyne (PWR) proposed using a derivative of the F-1 engine in the competition as a liquid rocket booster ... The F-1B engine has a design goal to be at least as powerful as the un-flight-tested F-1A, while also being more cost effective.

> Developed during the later stages of the Apollo program, the F-1A was test fired, but never flew. Several were crated and stored by Rocketdyne (later Pratt & Whitney Rocketdyne). The company has also maintained an F-1/F-1A knowledge retention program for its engineers for the entire period the engine has been mothballed.
