Random Dungeons Please

Can We please have some sort of randomness thrown into future dungeons? They need to have a sense of adventure since this is a final fantasy game. Please Make personal suggestions below.

Here is my basic suggestion:
-Have the dungeon only be 1 or 2 bosses needed to beat it, but have 7+ bosses in the dungeon.
-RNG will chose the path you take throughout the dungeon so you do not know which boss(es) you will get from the start.
-The way I imagine it is make it some sort of castle with certain paths being blocked by debris or the floor crumbling and leading the party into the dungeon.
-Make the dungeon itself level sync to lowest player in the group +2 levels so all levels can play.
-Don't let it drop amazing loot, just tomes (for players high enough to collect them), good looking armor (for the wardrobe feature) and vanity pets.
-Anything that adds a sense of adventure to the monotony of grinding tomes for the level 50s.
