Random Throw Creation Mod ?

Whilst playing a resource gathering and civ building board game recent night (cough Catan cough) I thought about how interesting it would be if different villagers generated resources at different rates. There would be an increased element of luck and unpredictability and successful players would be those who could adjust on the fly and roll with the punches. Every vill would have a random gather rate assigned at creation, somewhere between + or - 20% of standard. To stretch ‏‏‎ this, you could do the same thing for military units attack, armor, HP, etc. You would no longer know with almost certainty the outcome of any given engagement by simple count and type of units and upgrades. Flipping on a mod like this would de-emphasize executing perfect build orders or going up at the perfect time or rushing with exactly the right number of units. I can see why this would be a terrible idea for the pro scene, but for casual mid Elo players (like myself) this mod option would make it more “game” and less “train”.
