recycling old content

Could we please see all the old raid bosses again?
I would love to see twintania or bahamut as a hunt mob.
With full mechanics of course. some of the work is already done right? models, sounds, animations. just would have to scale it differently and whatever else it is you guys do.
please up vote if you wanna see old raid bosses walking around the map.

I'd rather them use all those other final fantasy games they have worth of content. Crystral Chronicles even is coming up from the looks of it and there doesn't seem to be a song from the game coming with it or even some weapons. Wouldn't you rather fight more old bosses like ultross?
