Hostile mob characteristic variants

Have different variants of hostile mobs in the different biomes on where they spawn. For example, the ravager we have in game, if spawned in the snow biome was slower but more health, or if spawned in the desert, it would be slow and low health, if spawned in jungle was fast and low health. I just think if we add different variants, we could also add different characteristics of the mob to make each biome with those mobs feel different and new. Would like to see other mobs as well, for how differently creepers, skeletons, zombie, etc. would change depending on where they spawn.
