The fields of the profile used as search default have to be public

I want to use a profile as default search result. This is clearly a feature for logged in users, however, the fields have to be made public to work.
To be able to use a profile as the default search result, it needs to work for Admin and Users only fields

I have hacked 3 files to make it work:

templates/CRM/UF/Form/Field.tpl (line 155)

UF/Form/Field.php (line 575)

Contact/Selector.php (line 185)

However, I don't know if the selector is used elsewhere than for the search result in profile, nor what security risk is there to add the Admin fields.

Advice ? What is the right way of implementing that ?
