Qaiser,
To be honest, I'm not sure why AC would tell you this cannot be done. I can think of only two reasons why they would say that:
1. They do not have the expertise to do it themselves.
2. There is a special thing about each AC database that makes it unique.
You should at the very, very least be able to get demographics in. I'd like to work with you on this. Send me a PM sometime.
