This would be a very interesting thing to implement, craters, filled with water or not, would be an interesting feature, especially if they contained small, not quite epic, materials and meteor fragments. There could be some unique animals, or have it returned to normal/act like a desert badlands.
If they're more than geological and can fall during world gen, the same could be true, but it would leave a blight of desert of a certain size But not affect the climate beyond that, else it would be hell to generate, especially from a parameter set. Increased volcanism in the region struck would be nice, a few small magma pipes and pools in the region. It could destroy any nearby cities and towns as well, creating ruins farther out and destroying all nearby, Dwarven halls may be exempt from these effects.
If it is possible to have happen during game play, outside the region the player is currently viewing, there could be a heat wave and dust storm across the map, acting like a wall of infinite miasma and leeching into structures, extending a distance relative to the meteor's size, even across the world, which would kill everything caught on the surface (outside, light) and raise the temperature up to the level of magma. This would be possible to ride out underground. Less destruction from smaller/more distant meteors.
A large impact on the same map as the player's fort/adventurer would potentially destroy everything above a certain Z level, and leave a large crater around the point of impact. the smallest impacts may leave only a small spot of obsidian down a z-level or two and start a wildfire. Heat could also be relative to size and distance.

As per the metals, I'd say allow for a stronger version of iron and nickel, Mithril from the dig deeper mod in the core, names are meh.
For creatures, HFS could arrive after the impact wave, or mutilated/undead versions of normal wildlife, from many biomes downstream, in a swarm from the same edge as the wave, maybe more than once, maybe not right away either, it could take them a season or two, and they could act like usual enemies and siege you. Zombie siege... Allowing this plague to occur in a handful of your own survivors would also be interesting. They could hang around in the craters for centuries if during world gen. And spawn from those that land at the doors to your fortress, in swarms, maybe with quite a few just leaving entirely. And let them wield precious and powerful weapons! If there are any special creatures of course.

Fit in procedural generation wherever possible, just for the hell of it if that suits your thoughts.

I've never really cared about the color of my stones and usually look for something other than the primary layer stone for furniture and such. Microcline is alright for that.
Large clusters should be made less common or less densely populated to combat their ability to irritate.
I'd like to suggest a more dynamic way of forming the clusters, so that it's not just a single oval-shaped blob. Maybe forcing a 50-60% chance for each tile in that blob to be of the cluster's material and the rest of the percentage to be the layer stone, without changing the placement of small gem clusters and the like within that area? Or letting small tentacles of the material to shoot out from a central point or line? That could all be made into new cluster tags I suppose.

This must just be a bug do to their having grasp-enabled pincers. Their raw doesn't include the [EQUIP] tag, but it may be because your axe got caught in a wound and it pried it out, and continued to attack you while still grasping it, which conceivably could act like it's wielding the axe, but that's still pretty unusual.
If you modded them to have the [NOSTUCKINS] tag it should never happen again. Can't find their raw file though except on the wiki, so I'm not sure where to look to help with that.

 

Hold the phone:  Vampiric plants?  What and why?

It just seems like a spur of the moment "lol its awsum!" thing completely disregarding reason.

In other words, it's absolutely dwarven!

Anyway, spraying my enemies with the wackiest things I can find, even if it just makes them angrier/humiliates them, would provide quite a bit of amusement, which is the entire purpose of games, isn't it? and the 'spray with something and immediately feed to something terrifying' (carnivorous plants) idea would be utterly hilarious. (or extremely disturbing if you think about it literally)
