With everyone’s approval, you can declare your weapon systems to be splitrange. For purposes of building your frames, a split weapon counts as two half-systems, one of each type. A split hand to hand/ direct weapon counts as half a hand to hand weapon system and half a direct fire weapon system, for instance. You still aren’t allowed to have more than 2 systems of each type.
A split-range pistol might add one red die at direct fire and one red die at hand to hand.
A split-range scoped assault rifle might add one red die at direct fire range and one red die at artillery range.
While this rule is quite commonly used with MFZ players, keep in mind: You sacrifice reliability for flexibility.
