Would it be possible, practical and balanced to include a feature in the game which would allow you to distribute food from your more food-rich cities to those with small populations, or to ones where you want a particuarly big city for some reason? That is, if a city is still working food tiles after you apply Avoid Growth and has not reached its maximum size, could this surplus be spread around your empire? The most obvious use for this that I can see would be to make viable cities in otherwise inhospitable climates (ie, desert or artic), but I spose it could be used for beefing up core cities as well. It could even have diplomacy implications, where the surplus food could be traded between civs.
As for implementation, I envisage either a late game tech like refrigeration granting this ability, or for it to have tiered introduction (ie, techs later and later in the tech tree allow for a greater amount of food to be sent to cities).
