Let's see... who else could be repurposed into a guildmaster and get some more plot...

I feel like making Lone Wolf the pickpocket into the thief guildmaster is a no-brainer. Once you let him out of jail, it could turn into a whole series of encounters where he tasks you to steal shit, but then at the end he double-crosses you and steals everything from you, and you chase him down to find he's the master of the thieves and this was all a sort of hazing/initiation ritual. Could be fun.

The Black Mage guildmaster should be a cameo by Matoya from the original FF. I have an extremely obtuse reason for wanting this—before FFV's initial release in Japan, there was a promotional album called "Final Fantasy 5+1" and it contained 5 preview tracks from the OST, plus one bonus track, which was an arrangement of Matoya's theme in the FFV sound font and I just really like it and think it would be fun to include her as an homage.
