I was wondering if the following setup is currently possible?

Have 2 content profile types: Content Profile Type A & Type B
Be able to see the fields for both content types at 1 edit page like below:

Edit Profile Page
Content Type A Fields
Content Type B Fields

Reason for this setup: I would like fields in both type A and type B to be required. Content Type A will be required at registration (includes first name, last name etc), and Content Type B will be required if user decides to create type B for more access to the website.

This allows me to have some info on the user such as first name and last name, and get additional info if the user decides to create a profile for additional access which requires more required info.

I am unable to do this in one content profile type because fields not required at registration are not required after user is registered. I need specific fields required after user is registered if they want more access.

However, for convenience sake I want the user to be able to edit all their info (type A and type B) at one screen.

Thank you very much in advance!
