You should make it in the very rules of being on here that you shouldn't be allowed to make threads of the topic of mods in any way since it's impossible. If there's any moderators that read this post. Maybe they can add DLC content, which you can buy, but no "mods". Because for Xbox, Microsofts terms of Service don't allow modding of the game and I don't think Sony allows modding either. If this applies to all consoles, then it wouldn't happen.
In the menu to create a world It'll ad a "Mods" button under the texture packs and you could turn on each one individually for that world. Or 4J could get permission to create a console version of really popular mods like galacticraft, the lucky block mod, or the like. It'll just add new weapons, ores, mobs, biomes, structures. It would work the same way other dlc's add stuff like in dead island the dlc adds new weapons and locations. It wouldn't be illegal because its not modifing the game itself. Why not create a way to make a mod like a dlc? You'll create it using an editor or like you would for pc edition but using console syntax (if that makes any sense) Then send it to an automated system to 4J or mojang or sony of whoever and show it as a free dlc for minecraft. I know that people want a way to mod console edition minecraft. Quote from ELVIN_MAGIC_MANI'm posting this in ps3 because thats what i play on.
