More death horses variants for the new update.

Hi, for the new update, I'd like you to add new variations of zombie and skeleton horses. These new variations would come with their respective mob, for example, the wither skeleton horse spawning with a wither skeleton on it. Here are my ideas for variations:

Zombie Horses:
1-Normal: The current Minecraft horse, mounted by the normal horse with the spear.
2-Desert: This would have a more terrifying touch, with bandages and white eyes (similar to a mummy), and would also have the desert zombie variation.
3-Snow: This would be like a normal zombie horse but frozen. This would have a new zombie variation, which could be a frozen zombie or a zombie in Eskimo clothing.

Skeleton Horses:
1-Normal: This would not only appear on skeleton riders, but could also appear more frequently mounted by a skeleton. With this change, I would change the skeleton riders to make them more difficult.
2-Wither: This one would be black and would be ridden by a wither skeleton with the new stone spear and would spawn in the Nether.
3-Snow: This one, like the zombie, would be frozen and would be ridden by strayders.
4-Swamp: These would have moss on their backs, green eyes, and mushrooms all over their bodies (like the swamp skeleton), and would be ridden by the swamp skeleton.

P.S. It would be great if they were officially added to "illusioner" for Minecraft Bedrock and Java in this update, it would be a very fun mob and would make invasions more difficult.

Thank you very much for reading
