Ones I'm not sure about... I think they belong to the bat, but I don't know for certain:
Gentleman Ghost
Shade

Seriously a nice list, thank you for digging into this a bit further. I'm confident that Gentleman Ghost originated as an enemy of the Justice League, but I'm not sure if he was Batman's problem or not (that would be cool though). I think Killer Moth and Firefly are often assumed to be one character, which explains a lot. Hush I feel is more popular than people acknowledge lately, and is a consistent character based on the quality/popularity of Hush (TPB). Jason Todd.... well, obviously he is a big deal right now. Black Mask, I'm a fan of this ridiculously over-the-top character, but he still plays a back role (I'd buy a decent DCUC figure of him though).
You mentioned Batzarro, and I'm intrigued. I don't know much about that character to be honest.
