So following my trend of making Dragons tougher by increasing their Hit Points I thought "Why not Miraak?". So I did.
His level is twice as much as the player's and his health offset is 1000 HP (higher values now available. Pick your poision). And yes, it regenerates each time he succs a Dragon's soul. Have fuuuun~

This mod also uses McDabbing's "Consistent Miraak" head piece to change his head from a basic nord to the head piece he uses in every pre-boss encounter, fixing Bethesda at its Bethesdest. The reason I did this is because I already used "Consistent Miraak" and wanted to make a mod that increased his stats, but my load order is at it's literal limit, so I made a fusion between these two mods.
And yes, I tried to ask McDabbing permission via DM, but when I sent the message it appeared an error that stated that, and I quote: 

The following errors were found
The member McDabbing can not use the messaging system
This personal message has not been sent

So I can't contact him. Therefore, rather than assuming that he wouldn't approve, I chose to upload this mod and credit him for his work, hoping that he wouldn't mind as long as I mentioned him. He hasn't been active for a couple of years already, so I don't even know if he'll know, but I'm open to talk about it if he ever finds a way to contact me and if he wants me to delete this mod then I'll comply no problem.

But enough of that.
IT'S FAQ TIMEEE!!!

"I already use X mod that edits Miraak's boss fight. Is it incompatible with this?"
There's a mod named "X"? I'd assume that yes, it might be incompatible. I haven't fully tested it but there's a chance that this mod may ovewrite it or vice versa. I tried making a patch for "Stronger Bosses Overhaul" but it turned out to be disastrous due to my lack of experience so I ended up making a choice and prioritized this mod.

"The new head is nice, but... What if I don't want the increased stats/have another Miraak boss mod?"
Hey, no problem. Just download McDabbing's "Consistent Miraak" instead as it only edits the head (as far as I know). It's a must-have for those who use "Improved Closefaced Helmets" IMO. I just did this mod to save space in my load order.

"Um... Dude, Miraak remains unchanged"
Yeah, you have to place this mod's file at the bottom of your load order. Try again.

"Whoah! It works now! You're so smart!"
Why, thank you, simple mortal :)

"Wait, are you seriously using the FAQ to have a conversation with me again?!"
Yep. I think it's a healthy way to make new friends. FAQs should be used by the community to build bonds between modders. Why don't you tell me about yourself?

<Insert your answer here>
I'm not reading all that.
I'm happy for you tho.
Or sorry it happened.
