I would say it would be awesome if someone did a hack like this for the game
but I have enough trouble getting around to griding through the Floating Continent in all the versions (NES and DS both) that I would never get around to playing it to the end
Fighters don't sand on the back row. Miko -> Cleric -> White Mage would me my guess as to the thought path here. and Samura wasn't a class in FF3. My guess would be Sakyua = Ninja and Youmu = Magic Knight (only class in FF3 that could equip the Katana-like "Dark Swords")

The sprite is an edit of Kurayami no Kumo (Cloud of Darkness), the FF3 endboss.
Murasaki is written in kanji as 紫, which is Yukari's name too.
