I teach slap hitting from 10U to college athletes. I can teach a 12U or even some 10U to put over an outfielders head in just a few lessons. I wouldn't bank on your defensive strategy. Most elite travel clubs by 14U have slappers that can drive it to the fence ....slappers that can't.... aren't playing A level travel ball. If you want to play college ball as a slapper (at any level) you better make sure you can drive it to the fence or you won't make a team.
IME, there are a lot of pretenders out there that are benefiting from the assumption that all slappers have been properly trained in the manner that you describe.
