Just look how different games solved troop stacking:
Hearts of Iron 3: it depends on troops type, tecnology and above all Supply
Europa Universalis 3 (Magna Mundi) - Troop stacking depends on many factors: terrain type, upgrades, tecnology, National Ideas.
As many said before 1upt it's a deal or broke...
To me the only solution is going Full Panzer General: retain the 1Upt but with more smaller hexes, more movement for troops and multi-hexed cities. Given the "lightness" of Civ V it would ruin even a Norad computer but could turn out a very great game: immagine the fight to control a 7 hexed city with swordsmen advancing inside against pikemen while cannon barrages land from both sides.
