If you double the turns without re-calibrating the probabilities you'll get super-heroes, not historical generals: they will get the highest levels in their 20ties and then they'll get tons of other traits, also getting the highest levels within their life-span.
You may like it, but I feel it wouldn't feel historical.
(and re-calibration is rather laborious in the RTW/M2TW modding, especially for such an advanced mod)
2) how the players feel staying the whole campaign with the same generals. With 2TPY the change happens and the aging is palpable. You've got a young general with a bright future, but after 20 turns he's not so young anymore. With 4TPY is slows down much. Depending on how many turns the people play, you may stay only with 1-2 generations of generals, or you may see 5-6 (this is the number I usually get in my games, I tend to get bored with the games after 150-200 turns).
However, some people may like staying with the same generals, so it's a matter of taste.
