I have 3 avatars but only use one at a time. I wish I could combine the 3 avatars into one so I could have all the inventory in one.

It could look like choosing which avatar you want to keep. This then remains as an account (name, friends, account). The other avatars will then disappear or be deleted, only the inventory will then appear in the main avatar. The friends list of the old avatars no longer exists.

Through this function, Linden Lab would no longer have so many "corpses" that are no longer used.

You can also charge money for the service of combining avatars. I would pay up to $100 just to have everything in one.
