Well, it *is* possible, but would be pretty much completely custom code.
oUF could be your frame work, Stuf as well. (For the unit frames). The textures would have to be custom made.
For the buttons, any bar add-on with again the correct textures. (FFIV then)
FFIV would be doable I think, though I am completely unsuited to write it myself. But with enough time, yeah.
FFXIII will be harder, especially those skill buttons.
If I recall correctly, there *is* an oUF layout similar...
