There is another considerable drawback for the 12tpy system: the population growth rates would get way out of hand.

Now, the engine only really knows two seasons, right? The rest is represented by traits of the family members, that change every season. Is it possible to add in a similar way a building to each town, which represents the effect of the season on the population of the city. In the winter months, for example this could be a massive population growth penalty, signifiing the large mortality in those months.

However, it must be possible to script these "buildings" to change every month/season, just like the character's traits.
I don't have any knowlegde on scripting, so I can't assess if this is possible.
