A bit late to reply? I would have gone for 3-2-2-1-2 maybe:

----ST----ST------
-------AMC--------
----MC----MC-----
DML----------DMR-
----DC-DC-DC-----

Zonal marking will nullify the need for a DMC, your MCs and DCs will all cover him as well. My only worry would be your single player on each flank against his two.
