SSE Thrallbound or Bosses drop Conjure spell of themselves

[Zahnrad]

One of my favourite Skyrim mods is Vigilant, an interesting feature from it is every boss or mini-boss tier enemy would drop an item, I forget the exact name but it was something like "Fragment of Molag Bal" or "Fragment of Cold Harbor"

It essentially worked like a spell tome, and would give you the ability to summon that boss/mini-boss in combat. I was hoping for something similar to be expanded into the main vanilla and DLC aspects of Skyrim. Or in the very least, on the more prominent or notable humanoid bosses from a questline. e.g. Mercer Frey and Arcano.

Alternatively, an option to summon a new version of their corpse to use as a thrall (unfortunately Vigilant didn't have a cap on summoning the same boss multiple times which ruined the immersion for me personally)

 

I've seen mods that do the same with Named Dragons, but I'm unsure on if there are any other mods that do similar to a more expanded arsenal. If there are any others, I'd be interested in seeing them.
