Yeah, I like it that way. I intended for melee and ranged to be different anyway. 

Okay, so here's my current system:

Cool: As in clear-thinking, calm, rational
Hard: As in hard-hearted, aggressive, violent. Determines melee combat. 
Swift: As in quick, reactive, flighty. 
Sharp: As in smart, perceptive, educated. 
Steady: As in dextrous, unflappable. Determines ranged combat.

These stats range from -3 to +3. They must equal a net of +3. 

Handgun
Rifle
Bow
Thrown
Melee

These range from -1 to +1. They must equal a net of +1. 

As for how play goes, you just post as normal, but without the conclusion for whatever action you take. I, or a co GM will roll and announce the number result. The player then posts again, or edits their previous post? I'm not sure what would be best here. We roll with 2d6(two six sided dice) and add(or subtract) the appropriate stat, skill, and stress penalty. 

Stress pool:
Each roll of 6 or lower adds one to your stress pool. Stress pool resets upon resting(whether it's actual sleep, or just the characters getting a break. 

1-2 No penalty
3-4 Penalty of -1
5-6 Penalty of -2
Above this all actions get -2, and players should have their characters act accordingly.
