Actually, there will NEVER be mods or addons to console Minecraft due to copyrights and/or related issues. I rather stick with rules we have for console Minecraft, otherwise I would be banned if I add mods.
Guns retrospectively are bad anyway. I would not want my young kid playing a Minecraft game that had em. Bow and arrows are one thing, so maybe add more bow types for long range or short range archery. Speed and power depending on the bow type, so in example in all this maybe have a crossbow/bow feature. The bow we have now in console could be modified to changes and renamed maybe opening a option for crossbow which would probably be short range and power, maybe speed then you got your let’s say a longbow for long range and power, maybe speed too
