Would there ever be a way to do halves for a loss/win, 0.5 loss - 1.5 loss for example?

Based on a combination of score, cs, and apm (actions per minute, if there is such a counter?). That way someone trying and playing well could eek by with half a loss while someone afk'ing or intentionally feeding would get a loss and a half (1.5). And vice-versa for a win? I know it would be open to abuse and shake up the entire system but ah, wishful thinking :/
