I like that style, I really do, but there tends to be two problems with that: 1. Super-strong hostile NPCs are often lore-breaking. Why do the Forsworn not run Markarth when their demigod Briarhearts are individually strong enough to kill all the guards in any given Hold? Just as an example of what I mean in a strictly unleveled setup, Skyrim Unleashed was my first de-leveling mod, and the presence of OP Archwizards who spam ice storm and fireball in every single mage dungeon was just too hard to believe. Why do they live on the fringe of society if they're strong enough to conquer it? I really enjoyed that mod, especially its take on level scaling (I think the author got it just right, as enemies scale, but they get a head start and scale slowly, so eventually you outpace them, but not till you're level 30 or so, and if you use the Uncapper for slower progression, that can take ages). But I just couldn't buy into the strong enemies and weak allies everywhere. 2. On a perspective that's strictly gameplay-related, it makes playing with followers incredibly difficult, even if you're chock full of restoration magic, since they constantly fall to 0 health, get back up, and fall to 0 health again, but you can't leave them behind.
