Sift Dimension Structures

I have (in my opinion) genius idea for how to make sift dimension more intresting. What would you think about adding another boss to minecraft. Giant sculk castle in the sift dimension (just like nether fortresses in overworld in minecraft legends) with really really hard boss that drops one special item that allows to upgrade our tools and armor to like sculk one, after the netherite or something similar. The castle will be humongous and have a bunch of op loot in chests (like a bunch of diamonds and netherite perhaps) and will be based on ancient city with wardens as a gurads to protect king warden or something else sculky type boss. I would also want to see more structures like in the minecraft legends (like ruined portal with ruins of a miniature nether fortress or bastions). Also for sift structures I suggest adding cobbled ancient cities with one or two chests surrounded with sculk for the "transfered from the overworld" effect just like with big castle.
