Cant take Grimebeorn in Halls of Thranduil as a historical allies even if Thranduil is in the army or the army leader. And Thranduil needs to be the leader even if Grimebeorn is added.
The best solution must be to add him to Halls of Thranduil so you can add him but if Thranduil is not a leader it will give an error.
It must of course be possible to add beornings under Grimebeorn when he is added.
