Combining the FFVII forums wouldn't be a great idea anyway; the normal FFVII forum is busier than all of the other game-specific forums, and is a lot busier than many of them to boot. If any change was made, I'd say stick FFV in with the first four, or find some way to combine the less-busy forums like Tactics and Crystal Chronicles. It's not really bad the way it is, though.
EDIT: Why do the Tactics games really need seperate forums anyway? They could be combined easily, and neither is very busy. I don't see how it could cause any problems, unless Cid wanted it that way like he did for 1-5 or whatever.
