An idea of a scene of Bruce Wayne back on our time in the Batcave looking at a collection of different batsuits, very much like tony stark with the armors, crossed my mind. 
Batman has had several batsuit designs as with batmobiles and different bat devices and it is known that he keeps some previous batmobiles in the cave, why wouldn't he have the previous batsuits there? He cannot toss them just anywhere. 
I would really like a scene like that once Bruce is back.
