Override the Edit profile form allowing edit of contact fields

Question

Each user in my Joomla website has an associated contact, with photo, link, and bio (in the miscellaneous information field), etc...

I would like to override the edit profile page (com_users/profile/edit.php), disabling the user profile fieldset, and instead using a contact profile fieldset, with selected fields from associated contact.

How can I add those fields to the form in the edit.php file (and be sure that those fields will be actually updated on submit)?

Answer 1

I would override the profile model with a plugin:
