Change mobs/blocks textures and poses with procedures

I need to change textures and poses of mobs and blocks using textures, I do not ask for animations like gecolib, I need to change textures like angry bees and a stoves, and change poses of mobs like dogs or the same zombies that can raise and lower hands.
I think if the mcreator team tries to implement these functions, then the mods will become better and will be closer to the vanilla style of minecraft, and at the moment, vanilla mods are very popular, like the  alex's mobs or mods of team abnormals.
