How would you feel if FFXV used an evolved Active Dimension Battle (ADB)?

I know this is a little off topic, but i've been wondering. What if the FF reveal at E3 isn't FFXV at all, but rather Codename Fortress? Remember that highly ambitious action games that Square took back from GRIN?

It would make sense if they plan on using the FF12 director.
