Sadly I don't think they will. This is nothing to do with skillsets. It's more to do with costs. Surely a trained person on the same type will be cheaper. Milk it now for when it all changes the same cycle will return.
Right now - if you can't find the crew having the same type ratings - then it goes to the second level down the food chain, TP guys and girls.
When that erodes - it will be instructors or cadets....hopefully
