 Going back to the crap-a-pults, a nice addition would be catapults throwing corpses to spread disease, like in the middle ages, although then it was mostly used by the besiegers.

 Haven't read everything, so this might have already been suggested, but I think it would be pretty cool if when say a city following their religion had been captured elsewhere in the world, very devout members of that religion would gather, trade away stuff in their temple for equipment and go off on a crusade to take back the city, which would give extra reason for players to get involved in religious affairs, for better or for worse. 

 Okay thanks.

 It would be interesting if DF had a science system, but instead of having a tech tree like in most strategy games, there there would be knowledge about a certain thing (stored as books in dedicated buildings and spreads as rumors in between individuals), the more knowledge there is about a certain thing, less/less talented scientists are required to discover properties of a thing. Properties have 2 uses: 1)giving more knowledge about the thing they are a property of, and 2) creating a new use for the thing when inventors are assigned to create new designs. Properties could also be discovered during world gen, mostly basic ones such as cloth burns, glass shatters and so on and so forth.
 
For example, your fort has 2 properties of glass, 3 of booze and 1 of cloth, 9 of steel, 4 of wood and 7 of cobwebs. You then assign a inventors to procedurally create a new design by mixing the properties, so he could for example invent the Molotov cocktail, the glider or whatever. One problem I see is how the game will come up with names for the inventions.

TL;DR, Scientist discover stuff about things which allows inventors to create new designs.

 This is awesome.

Stuff like plump helmets, cave wheat and others. they are only used for stills and food.

 Ok that's fine with me, although most of my post was quotes.
