As long as the arrowed ML/MR are able to advance as intended, you will get an approximation of the 4-2-2-2 Hexgon, but this all depends on what/how your opponent plays. You can only try it and see how you fare, 4-4-2 has in the past been a pretty powerful formation no matter what it is pitched against.

You will need, at some point, to get some AML/AMR players as they can be the most useful positions on the pitch, particularly if you are going to play V formations or their near-equivalents (4-3N-2(AML/R)-1, for example).
