A Skeleton Water Varient

We have a swamp, desert, cold, and nether skeletons. Although, one varient is missing. An underwater version of the skeleton. The zombie already has the drowned, so why not the skeleton. This new mob would be called the Merleton, based on the mythical skeleton mermaid. The same thing with the zombie, if the skeleton is underwater for too long it would become a Merleton. The merleton would be able to swim under water. It would also be equiped with a bow, but a really rare chance of being equipped with a drowned bow, which would be two times powerful than a regular bow. If a merleton had a drowned bow and was killed, there is a 45% chance they'd drop it. They only stay underwater though. Merletons also fight with Drowneds. 

I really hope Mojang adds this to Minecraft.
