I don't know man, Ito said he made this game to be the real complete version of FFXII and implemented many game fixes and gameplay changes they couldn't before and the job system does seriously change the game set-up in such a way they allegedly did go through and change the game's difficulty curve. I mean the boss rush mode alone would be painfully easier with the old License Board as opposed to the new system in place.

I'm not saying they couldn't but this is Ito and he is most likely not going to change anything except maybe a few more bugs he learned from fan feedback. I honestly don't see a reason to do this either. Ito was not happy with how the original system turned out and was received, so I really doubt he would want the original back in, especially considering all the work he put into the IZJS version with a skeleton crew.
