I don't have a definative answer for you, but I'd be happy make a couple of suggestions you might want to follow up on.
First, call the examining agency you're dealing with now and discuss this with them.
Second, KPMG has a division (I think it's out of Chicago but I'm not sure) that specilizes in "Funky" CRA reporting institutions. Amy Matsu is a contact there who could probably help you out as this type of thing is her specialty.
(Disclosure....For anyone who thinks I'm advertising for the company I work for...I'm not an employee of KPMG

and I don't play an employee of KPMG on TV...nor do they pay me to use Amy's name

I just know she's dang good at this stuff!)
