Well, we do know interdimensional travel is possible from the various cross-over events, and that it can even be under one's control (assuming Shantotto is telling the truth in her event). However, that's transit between totally different worlds, not different versions of the same world. Nothing in the game suggests that there's different alternate versions of the XIV universe, but then nothing says there isn't, so... presumably, you could do it, but you'd need to be aware that not everyone will accept it and a fair number of characters will act ICly as if yours were crazy.
