Now, of course, the main draw of XI and XIV were that you could switch classes, so everyone will end up doing that - but most players aren't going to level everything. Instead, they'll have end up with PLD and BLM, or DRG and WHM, MNK and BRD or something.
I'd love to see a system like the one you described but I'm not sure it'd work. It would require a bit too much preparation work for the average player before you can really be optimal at a given job at level cap.
