The simple idea would be to mod cavalry to have a higher upkeep, especially the romans, who basically would have paid a bit more for subcontracting their cavalry work to mercenaries. Of course, while a human might react to this by reworking the composition of their armies, I bet the AI would just bankrupt itself that much sooner.
