The Relocationing

Say a person who wants to play a Blizzard game, but doesn’t own the app, knows someone willing to share their account, like a parent or friend. After a while, both want their own separate accounts. However, both want to keep the things they’d earned in their games, as well as event items they’d never get again. Is there a solution to this? Maybe, if there’s 2 accounts, (Account A is the one with the collectibles, and account B is the one with nothing), account A can choose to give the contents of any one of their games, and give it to account B. This way, they can have separate accounts, and still keep their things.
