It would actually make sense, considering how the Japanese market is, but I don't think, unless they do totally different versions or both of them return to basics, that FF as a series is as suited as DQ to do that sort of thing, as DQ has barely deviated gameplay-wise (and I love it for that, too).
I'm really dying to see what kind of setting they've got in store for us, and who the character designer is. I hope it's a new, young one, actually. Or Amano and try to do justice to his style, but that's a pipe dream (and I don't really know how pleasant the result would be).
I just hope that after some years janitoring, Ito has had enough and wants to show people how to make a game. Dude has an impecable career: he is, imo, the most valuable asset S-E currently has, considering what he's directed and what he has created for the series. A new, big IP would be great too.
I see them announcing this in 2018 at the earliest, though
