Well, i've no intention of attempting such a task, because, as you just stated, it be either impossible or would have to be so streamlined that it would barely be recognizable. Its fun to play around with theory though. Besides, there's nothing stopping us from using stuff from FF6 as the basis for a stylized FFT patch. (say one that didint mess with the story of tactics, other then to raise the overall technology level to that of FF6, so references to things like 'the lost age of airships' would be changed to a reference to 'classic airship models' or something, and Magitek armor units would take the place of the archaic/ultima demons as common special foes)
