Absolutely! I've successfully built and run such training.
Most things are trainable skills. For example, I'll never be able to run as fast as Usain Bolt, not by a country mile. But, if I develop my running skills to their maximum potential, I'll be able to outpace a pretty good chunk of the rest of the population.
Same goes for communications, programming, whatever. You might not have what it takes to be The Best In The World, but most people definitely have the potential to become unreasonably competent at a thing, should they choose to put in the work.
