Don't think that's possible. Transferring to another device would mean wiping the data on that device forever. You might be able to do this with a third device by you transferring to that third device, your brother transferring to yours, then you transferring again to your brother's. Not sure if you can transfer more than once though, and the effort might not be worth it anyway.
