sounds cool! I’m running a Monolith game at the moment using some home brew rules to run it in a 40k Dark Heresy setting. I already use a house rule that for solid projectile weapons, if you roll max damage the clip is empty and you have spend the next turn reloading. Ammo takes a slot, but you can put as many ammo clips as you like in that slot.
I like the idea of different damage types
