I could e-hug you, Byrth, but I dunno if you'd be comfortable with that. I love the idea and wholeheartedly support it. I've never been on the "people should be forced to specialized just because" bandwagon. As you say it goes totally against the freedom the job system gives us in the first place. As I've said before it's like they decided to jump the shark at the end.
The only limitations that would keep them from doing this are Tanaka Limitations. Unfortunately he's less flexible and has less memory than a PS2.
