But that would mean either using them in a different capacity. Mission wise because of how they handle heavy weapons in this one. The geth rocket troopers use M-77 so it makes sense to see that one. As for the Beam and Projector, it could be that they might change the weapons class, turning them into rifles, but doesn't make a whole lot of sense with the beam.
