Can I customize the Members Directory and autogenerate 1 member post?

If I use Members Directory to document an organization's members and provide certain members an "enhanced member information page", can I modify the required information in the membership form, auto-generate their one (and only) post containing some of that information along with a form for updating any additional information, and customize the directory listing? Additionally, does the search feature of the directory lend itself to searching based on different fields, including geodata, such as 5 miles surrounding X address?
