Possible to add Luso and Balthier to PSX?

[Verdeni]

If it is, even if people don't necessarily wanna use them, that makes two more formation sprites/portraits.
So... Is it possible?
What about the Dark Knight and Onion Knight slots in the job wheel?

[philsov]

it is not (easily) possible to add ANY new jobs into the game.  Something somewhere must be removed first.  

Also there have been no new advances into permamentally expanding the job wheel, much less a way to actually make OK/DK conform to their PSP standards in terms of unlocks, abilities, or stats.

otherwise FFT:C would probably have already adopted these measures.

I knew that too. xD

Has anyone ever checked the .BIN files that have to do with the job wheel, and checked for major differences?
Now I really wanna figure this out. >,>
