The difficulty though is to mix stuff like this, it requires development. Development time that would have to be taken away from doing anything for the main game. It would be a pretty serious compromise when they don't even have enough resources for the main game as it is, unlike Activision Blizzard which already has money printing machines and can pretty much do whatever they want, even patch their old games with new stuff.
This would require the FFXI team to get an influx of resources that would be pretty disproportionate to the amount of money the game presently makes.
