There's a good number of mods out there that deal with turning the Unarmored skill into a more useful one. The best I've seen thus far handles this task by granting Sanctuary bonuses that increase in magnitude as you level up in Unarmored. It's a good method, since the premise of Unarmored is that your character is mostly dodging attempts to harm them, rather than just taking the hit and having it do less damage.
However, my preference is to have a character that, despite not being covered in high quality armor, can shrug off a good portion of the blows they receive. Not just because their HP is ridiculously high, but because their hide is just that f-ing tough. (Being able to utterly dismiss strikes from sub-standard weapons at a certain point would make a nice addition to this, but that's for anther time. )
To this end, I've begun toying around with the game settings, trying to raise the armor rating one achieves at any given level in Unarmored. Thus far, the results have been encouraging:
First Attempt
===========
+ Changed the value of game setting "fUnarmoredBase1" from 0.1000 to 0.1001
+ Changed the value of game setting "fUnarmoredBase2" from 0.0650 to 0.0651
Results: @ Unarmored 35, AR is 7 (same as without the mod).
Second Attempt
=============
+ Changed the value of game setting "fUnarmoredBase1" to 0.1100
+ Changed the value of game setting "fUnarmoredBase2" to 0.0750
Results: @ Unarmored 35, AR is 10. @ Unarmored 100, AR is 82.
Third Attempt
============
+ Changed the value of game setting "fUnarmoredBase1" to 0.1200
+ Changed the value of game setting "fUnarmoredBase2" to 0.0850
Results: @ Unarmored 35, AR is 12. @ Unarmored 100, AR is 101.
Fourth Attempt
=============
+ Changed the value of game setting "fUnarmoredBase1" to 0.1500
+ Changed the value of game setting "fUnarmoredBase2" to 0.0950
Results: @ Unarmored 35, AR is 17. @ Unarmored 100, AR is 142.
Fifth Attempt
===========
+ Changed the value of game setting "fUnarmoredBase1" to 0.2000
+ Changed the value of game setting "fUnarmoredBase2" to 0.1000
Results: @ Unarmored 35, AR is 24. @ Unarmored 100, AR is 200.

My target for the armor rating attained by an Unarmored skill level of 100 was initially 166 (equal to wearing a full suit of Glass @ Unarmored 100), but now I'm thinking I might aim for the 200-250 range, since I can't really think of a good reason to limit Unarmored players (especially myself) to so far below what Heavy Armor users can achieve protection-wise.
Obviously that won't be the end of it though, since such alterations will have some rather adverse and undesirable effects on just about every NPC in the game (I imagine). Originally this turned me off to doing this mod, but after thinking about it, and finishing Demolank's Shop, I've since realized that those potential problems can probably be rectified if I just spend some time with it, make plenty of notes, and test, test, test. I also, if this works out well enough, want to expand upon this by creating related abilities (such as resistance/immunity to Normal Weapons) which the player can earn in some way (probably through leveling up).
Any thoughts/suggestions/questions, are all welcome.
