Is it possible? I imagine I should I add a full name field to the user?
To do that you should override the theme_user function. There is an example at http://programmingbulls.com/how-display-fullname-drupal-instead-username-usi... showing how to use some profile_name_last and profile_name_first fields in the profile to replace the username with those two fields.
Hope that helps.
