biome based Nether fortresses

They should make new and better loot for the fortresses and should make the fortresses and their loot  generate based off of the biome that they are in.

For example, if the fortress was in a warped forest it would be made of warped nether bricks, it would generate in a weird, warped way, almost like one of those wacky mazes with the upsidedown stairs. The loot could just be good loot or with each biome fortress their will be a very good item specific to each type like a gravity flipper item (unrealistic but just an example) in the hardest part of the fortress alongside the good loot.
