I can't see a crossover between wheelwright and cordwainer, even less so if you consider that each apprenticeship lasted 7 years!
I have an instance of there being no "cross overs". My first job was with a very large heavy engineering firm making earth moving machinery. It employed skilled men over a large spectrum of engineering and carpentry. There was a recession in the early 1960s and I especially remember one pal who was a time served engineer boilermaker (the highest paid engineering grade) who was one of the unlucky ones who lost his job on the Blacksmith Shopfloor. He was immediately approached by one company who offered him employment as a blacksmith. The company was a local brewery but he he turned down the offer because he didn't know anything about shoeing horses or fitting metal rims onto dray wheels.
