Would be great to see same show setup with CNC machining or manual machining challenges. Really skilled guys show up and have to make things with random material, time limits, etc..
Maybe a show by "Skills USA" who does competitive skills competitions around the world. It works with High School age kids to find the best of them. USA gets beat bad sometimes by countries that have kids break off early High School age and into apprentices and have lot of real world experience to compete with at that age.
