I've been thinking recently. The combat rules in 3.5 are actually pretty decent, both realism-wise and to use. But using the d20 system to adjudicate skill checks has been frustrating me to no end. You roll on the d20 is a colossal proportion of the total score, especially at low levels. A first level character with a Listen skill of 5 (which is entirely reasonable) has something like a 25% chance to hear a character with a Move Silently score of 15. Which is what you'd see on a level 7ish master thief.

Now, systems that use a dice pool are comparatively excellent at resolving skill checks. You have a number of ranks in a specific skill (say, tumbling), and roll a number of d6 equal to those ranks when you use the skill. A certain range of numbers is a denoted a "success." You need a certain number of successes to do certain things. When you have opposing rolls (Stealth vs.Move Silently), you each roll your skill and compare the number of successes. Some systems use 3-6, others 5-6 as a success.

What I was wondering is, has anyone tried combining the two in 3.5? Use the d20 combat system with dice-pool style skill checks? Without any changes other than replacing the rules behind skill checks? What range is best for determining a "success?" How/where did you set the number of successes for each DC? At 10/15/...35? Should that scale linearly? Or, is there a better way?

I was thinking 5-6 is a success, and a DC of 10 is one success. DC 15 is 4 successes, and it scales linearly. But I haven't had a chance to try this out.
