Orkut like 'Friends' plugin

I would love to have a small change on the 'friends' plugin. The present one works more like 'following'.

My dream-plugin would work like this :

If someone clicks on 'add as friend', the latter one gets a notification to accept it. And, when he does, his profile is shown on the 'friend' widget on the person who sent the request and vice versa.

 

Could it be possible?
