Modest Bodies is ready to go. Pedestals and Eternal Fashion are probably ready to go, but I'll need to doublecheck. Vampire Anti-Sobriety and Basic Adventurer's Pack are things I've done before, but will need to be merged in to Modest-compatible raws.
Accelerated and expanded plant features are both things I definitely want to do, but they'll take more work. I could probably get Accelerated done in a weekend or two (thanks to Igfig's work in the original Accelerated Modest Mod), but Plant Features is going to take weeks, maybe months, depending on how busy I am with other things. (Plant Features will not be compatible with Accelerated, by the way.)
Cat Damper, Skill Tweaks and Rubbless are super easy, but I don't know that anyone cares about them now that vanilla DF has gelding, rebalanced skill learning, and 1/4 as many boulders.
Seasonal Crops is not possible with the changes Toady has made to farming since in 0.40.10 or so.
I was thinking about a Reduced Yield module as well, reducing the number of eggs creatures lay, the units of booze from brewing, that sort of thing.
Other suggestions are welcome.
