Drown replace Zombies Spawns in Lush Caves

I think drown should replace zombie spawns in lush caves. They are litteraly a mossy/slimy zombie that I think would look great lurking around lush caves since it is a moist biome.

One thing that would be nice to change is that drowns in lush caves can't spawn with tridents or at least less frequently as to not take away an incentive to explore the oceans and because fighting them in tight spaces would get annoying.
