Like I said,
I don't think you need new rules.
A 1st level monk has flurry of blows, he could unarmed strike two opponents with each attack and say, "I try to smash their heads together!"
If he succeeds in both attacks their heads come together in a sickening thud and they both take the monks unarmed damage.
Also, rather than coming up with a new mechanic to reward a creative player, reward the creative player with bonus experience for trying to enhance play, or give him a circumstance bonus on his attack roll (It's in the DMG).
Much easier, keeps the game moving, plus it rewards creative players. Let your players know that by describing their combat maneuvers they can get bonus XP, etc. It can do nothing but enhance game play from:
Player 1: I hit for 12 points of damage
Player 2: I'll just 5' step here and cast my spell Magic Missle. 11 points of damage.
To:
Player 1: I duck under his blade and slash out with my sword, striking for 12 points of damage.
Player 2: Carefully dodging the blade of my opponent I begin speaking the words of power and feel myself fill with magic. At the culmination of my casting I point at my opponent and 4 yellow points of light streak from my hand to my opponent doing 11 points of damage.
