End crystal like animation

I am trying to create different types of end crystals

So my aim is to change the color of the vanilla end crystal and the size of it.

I Still want to keep the animations of the internal part rotating, rings rotating, bobbing on bedrock, obsidian, etc

Is there any way to do it in mcreator? probably animated blocks with blockentity?

I have never used these settings before so it would be very helpful if someone could explain.....
