Rarer,and Better Dungeon Variation

An idea that's been on my mind is that dungeons in Minecraft should have a new rare variation it would just be a dungeon that connects to other dungeons

• These dungeons would have the same box format that they have now,but should be connected  to other with 1 x 2 pathways
• these pathways would be covered in gravel i chose gravel because the new texture blends very well with the new cobblestone texture
• in this new variation you would have to mine the gravel to get to another dungeon which can also have variations these include:
• A slime dungeon which have some slime blocks on the walls and a slime spawner A spider dungeon which would have cob webs on on the corners of the dungeon and a spider spawner in the middle,finally a troll room which would have lava,or a witch hideout.
• There would also be chests in these dungeons which would have the same loot as the regular dungeons but would have higher chances of getting enchanted golden apples,diamond horse armor,saddles,enchantment books,or name tags
• And a new unobtainable block which would surround the dungeons that have not been explored(a dungeon that has not been explored is a dungeon with no torches on the mob spawner or the mob spawner destroyed.)After the mob spawner is destroyed in an individual dungeon the dungeon holder block would turn into stone
• The Dungeon holder block would not surround the beginning dungeon allowing a way for the player to get in.When the dungeon holder block is touched it would show the player the beginning dungeon
• This could also be an opportunity for a new boss/mini boss at the end of the dungeons which could drop a unique item as well as some good loot
