Believe it or not, that has been my task for a couple of years now and as you might imagine, it's far from over. While I never intended to include Batman's appearances outside of his main titles, I've pretty much indexed all the information available and required until the 90s. Had I not done that, your task would've been much larger and complex than you've experienced so far.

As for "membership" to the Bat Family; I'd say it's pretty clear who belongs and who doesn't.

That said, I acknowledge how daunting such self-imposed task could be and I hope you don't find yourself overwhelmed by the sheer amount of time and resources that you'll have to spend to achieve your goal.
