Frend cloning

My idea and the next one is to add a clone for the avatars, but in private/friend.
For example, I upload a personal avatar and I want to give it to a friend, but rather than putting it in public and therefore, I risk having it stolen, rip, I leave it in “private”, but I have an option for him to clone me with a whitlist system to allow him to take it, clone.
It would therefore be to add an upload option in addition to the two that we currently have (private/public) to have a sort of dashboard to put, remove the whitelist and be able to block the avatar from people who have taken it without authorization.
I don’t know if everything is clear, maybe sorry for the bad English I’m not the best (thanks google translate).
Good day to you.
