Dual Shields

We've always seen Dual Wielding in Ace...however, I was thinking if Dual Shield is also possible, where the Shield can be equipped by a certain actor based on a class the actor is in. 

From what I remember, all equips are essentially tossed into the actor's equips array with reckless abandon, and only the UI actually stops the player from equipping anything anywhere. If you make a few tweaks to your equip screen, you should be able to just have it put anything anywhere, including two, or three, or four shields, etc.

EDIT: Now, getting a shield to act as a weapon AND a defense item might be trickier. I don't know how I'd implement that personally, I'm just pointing out that nothing stops you from making UI changes to make infini-shields.

So is there any way to do this though?

It's not much different from dual wielding.
