Pathfinder 1E DoaM for meaty-hp, sort-of-simulationist Pathfinder?

[Cadence]

So, if you're trying to run a grim-and-gritty sort-of-simulationist PF game... could DoaM actually be appropriate? Here's a first pass (whose damage values might not be very well thought out)...

If a melee attack roll is lower than the target's AC, but high enough to succeed on a melee touch attack, then the attack still physically impacts the target and causes nonlethal damage. Creatures that are immune to bashing or non-lethal damage are unaffected.

The amount of damage caused is determined by weapon type:
Light Melee = 1/2 strength bonus - 1
One Handed Melee = 1/2 strength bonus
Two-handed Melee = 1/2 strength bonus + 1

This is further modified by weapon size:
Tiny = - 2
Small = -1
Medium = 0
Large = +1

If the weapon is a bashing weapon then the "1/2 strength bonus" is rounded up instead of down. No damage is caused ff the final modified value is 0 or lower.

And then supplement that with the obligatory few feats that go with any game mechanic...

To me, the right way to go about this idea is instead an ability that lets you take 10 on attack rolls (say, once a round, perhaps more if you want to advance it). That actually ties up holes in how the system works instead of making them, and avoids all the weirdness of DoaM.

If I want to run a grim 'n' gritty Pathfinder/3.5 game, I tend to use this supplement. Most of the rules listed on the storefront are (if I recall correctly) modular, so it's easy to implement the necessary parts and discard others.

Isn't the size modifier already factored into the Strength modifier? I mean, you could just do Strength modifier worth of non-lethal on every touch, and that would get you very close to the same place with somewhat less hassle. (Also, I would suggest full Strength modifier because half of that is very often just 1 or 2, which is rarely worth tracking against something with 12hp or so.)
