IMHO, your idea is way too tactical. Civ is a strategy game, not a tactical game, and having to worry so much about the relative strengths and weaknesses of your unit combinations would add a tactical dimension to the game that wouldn't fit in with the rest of the game, or what the combat system should be aiming to be like.
