The above are not really Asymmetrical as such (they are what I call lob sided) and in the case you have above a DMC placed centrally would pick up that AM player.
A standard generic formation as the V would be fine.
Asymmetrical formations need balance to work those do not. IMOFocusing attack on the opposite side to your stronger defensive side is, well! ......... short of players, and that's being kind.
