This would involve a big rewrite to the xProfile component. It wouldn’t be an easy task and I’d actually recommend against doing it. Instead, perhaps you could disable the component and roll your own usermeta-based solution to user profiles?

The second ask — i can’t usefully contribute!

for the first ask

Assuming your new user fills in her/his profile fields on registration

Something like the following MIGHT work.

On FIRST login a user is redirected to say .$user -> user_login.’/profile/change-avatar/’;

then add something like this to the functions.php file of your theme

function alaiam(){

global $current_user, $wpdb, $bp;

get_currentuserinfo();

$user_id = get_current_user_id();

$firstname = xprofile_get_field_data( "First Name" ,$user_id);
update_user_meta( $user_id, 'first_name', $firstname);

$lastname = xprofile_get_field_data( "Last Name" ,$user_id);
update_user_meta( $user_id, 'last_name',$lastname);

$gender= xprofile_get_field_data( "Gender" ,$user_id);
update_user_meta( $user_id, 'gender',$gender);

$xdob= xprofile_get_field_data( "Date of Birth" ,$user_id);
update_user_meta( $user_id, 'dob',$xdob);

/*and so on.........*/

add_action('bp_before_profile_avatar_upload_content', 'alaiam', 10, 0);
