Echelon Question for Experienced players.

What would you think of a 3AR 1SMG 1HG squad?
Something like
SopMII, Welrod, Empty
AUG, Mp5, Empty
FAL, Empty, Empty
You can swap in and out whoever you'd think to be reasonable for 7, 4, 5, and 1 but would having something like either Welrod or Mk.23 be a good idea for a AR/SMG squad?
