Content from minecraft dungeons and minecraft earth etc.

All the content from minecraft dungeons like new weapon mechanics for example to fight the guards from the nameless boss you need a Glace because he has a Glace himself or something like that. Also all the textures , plants , blocks all the stuff from the dlcs . And about the minecraft earth part just the mob reskins in different biomes , because it would just make the biomes more interesting. If the problem is that there are to much mobs you could just make the biomes themselves a lot bigger.
