more water stuctures

I think more underwater structures would be good. some ideas I had were ancient bases with conduits in the middle, for example there could be a small one with a singular ring and some other prismarine things on top. I was thinking on top of the ring there would be stairs on either side of the middle of that side of the ring, then a prismarine wall in the middle and finally a prismarine rod which would be a new block that lights up brighter under water and the longer it stays out of water the dimmer it gets. The prismarine rod could extend the conduits range just by placing it in the conduits currant range. also you could add conduits to ocean monuments with 2 rings and prismarine rods could also be found there. finally this one would be on of the biggest structures called ocean cities with a 3 ring conduit, multiple prismarine rods, and being the only place you can get prismarine casings that protect redstone that breaks underwater and at the edge of the ocean city there could be empty nautilus stations where nataulises could be tied to a fence ,that's the same wood type as the nearest forest, then released using redstone and giving the rider food. if you think that getting a conduit without crafting it makes it too easy to obtain then all the conduit structures could just be broken.
