A new dlc for minecraft dungeons

A new dlc that my friends and I have been thinking about Exploring the new cave biomes. It would explore the 4 biomes, Deep dark/ancient city, lush cave,a new amethyst biome, and the stalagmite area. This dlc could also have 2 secret missions which would be parts of the tricky trials. In this dlc there would be a 1 new weapon one per level and 1 new armor in the Deep dark and the tricky trials. Artifact in the dlc would be based off the biome,one example for this would be a axolotl pet summon for the lush cave. Like the end dlc I think there should be new mobs in the ancient city. A problem that we thought is where to put the dlc. We could not decide if we should put it in the islands or make a new place. In my personal opinion this would be a fun thing to explore and play through. Hope you guys enjoy the idea!
