Consolidate financial Inquiry Responsibilities into one using only OAF pages?

We are looking for a way to consolidate all Inquiry responsibilities (AP, PO, GL, FA, AR) into one single responsibility AND only using the Oracle Application Framework pages. This would include concurrent requests as well! We are trying to move away from the Forms as much as possible because of Java and the problems we encounter with it. I know it's a big job but wondered if anyone has attempted to do the same thing.
