Any tips which mods would give me this kind of gameplay?

I've played vanilla 100+ hours and cleared legendary which was boring bulletsponge and me being insanely overpowered immortal thanks to enchanting. Unfortunally legendary difficulty is not for challanging yourself but to test your masochistic limits.

This is for my new archery build. My ideal mod would make it so:

1. enemies movement and attack is 2-3x faster. This is so you can't kite or abuse terrain.
   
2. It would take 1 shot to kill someone including myself. (maybe 2-3 shot if you miss all enchants+end items or tougher opponent).
   
3. Better crosshair maybe.
   
4. After your first shot from stealth mobs would recognize you 100% so you can't restealth or stay stealth anymore.
   
5. Possible spawn more mobs mod. But I don't want to go too crazy with it.
   
6. 10min cooldown on every single potion. (doubt it's even needed with 1-shot mechanism in place but just for good measure).
   
7. 
   

Well maybe 4 doesn't matter because I can just go away from stealth manually.

Hmm I could also maybe just add more mobs but don't effect their speed. I guess that could work too. I need test how it would work in theory tbh.

These mods would be ideal setting with perk overhaul because I can shoot slightly faster arrows with perk. And with alternative starting I have higher archery instantly like 40 or something. I would get straight into hardcore setting.

I would play this kind of setup without savescumming.

you could look into Requiem, if you haven't already.

It's not exactly what you're desctibing, but close enough I think :)
