Matsuno is/was the leader designer or director of FF Tactics and Ogre something, and is also the mentor of the current team's lead scenario writer (which means he already has indirect influence on the game). He is among one of Japan's most respected and heavily sought after game designers.
Yoshida wasn't receptive to the idea because requiring the black mage to keep a stock of multi types of weapons goes against their very philosophy of accessibility (ie, XI's infamous GTFO if you don't have X weapon scenarios).
Not a revamp, it seems. Just a suggestion.
