The wither needs more souls!

Hello MOJANG why don’t we add more features and character to the soul sand valleys? Like this following information .The mega wither: is made from soul blocks (down below as another topic in this request ) and whither 3 skulls (a new item the wither will drop with a 48% chance of being dropped) with the ability to slowly but efficiently corrupt the dimension it’s in into soul -sand/soul soil, the only way to stop the corruption is to defeat the mega wither and to do that you need to kill it PROPERLY! this means by killing then attacking the particles that it drops to stop if from getting 9 HEADS! Its attacks are simple, but deadly its first chosen attack shooting 3 whither projectiles out of each head at once. Then, as a second wave it will summon 19 wither skeletons all armed and ready for battle. .soul blaze: basically a blue blaze .THE SOULS ARE ESCAPING!: when ever you break a block of soul sand or soul block, you will ACTUALLY be able to see the souls escaping and head towards the surface towards the over world unless you have an empty glass bottle you can CAPTURE the souls and when you are NEAR a hostile mob, the bottle will glow brighter to let you know. .HERONRINES SOUL: no NO not HEROBRINE his SOUL will roam the soul sand valleys following you as a hostile mob only able to be in the soul sand valleys. You can make it go away by chasing it away with a regular torch but can’t kill it. Thank you MOJANG for listening to this idea.
