I agree with Zico that this area is beyond the realm of community support. To do what you're suggesting you'd have to fork oxTrust. And these are not features that Gluu would ever support, so you would have to maintain your own fork, and merge any future changes. Net-net, what you are suggesting is a horrible idea.
Far better would be to write your own application to meet this requirement. That way you can use the tools you are familiar with. You'd be better off modeling this data in an RDBMS or JSON database. And then have this new user management application render the information as an attribute of the user (i.e. use the `/Users` endpoint to add this data to Gluu).
oxTrust is primarily the admin UI for oxAuth. It's not meant to be a user administration tool.
