I get that it kinda goes against the idea of the weapon, but it would be pretty damn cool if there was a mod with variations of the weapon that shot bullets or maybe even rockets (for anyone who wants to be Iron Man). Perhaps a variant of the Displacer glove with something like the Lakelurk's pulse attack or plasma. From my fiddling with the GECK this seems pretty doable.
I'd be happy seing just a small blast from the glove really. Like a very short ranged shotgun that activates with punches and requires ammo. If you have no ammo, you do less damage, but still more than unarmed.
