I think the fossil collection is an excellent example of potential late game collaborative curios. Look at this recipe:

Petrified seashell from mining, bones from livestock or hunting, and wood from tree farming. Bones and wood are going to be consistently raised (assuming you have someone doing that), and the 6 seashells are quite an annoying(in a limiting, good way) order for miners, on top of whatever they're actually mining. This is a great design for late game curios, where you need large amounts of high quality ingredients from different industries. Garbage from one will tank the quality. Unfortunately in this example the seashell quality is the limit, can't spiral that.
The crafting abilities are something that could be adjusted here though I think. For example, look at the gemcutting recipe:

A wide range of stats and skills all required to raise gem cutting proficiency. A recipe with this complex of a softcap would be great for late game collaborative curios. At least someone in the village better be well rounded! Can't just log onto the mining/masonry alt and shat out a bunch of masonry curios, it needs a more well rounded character with more than just a few stats jacked up. We call those "main characters" in the biz. More curio recipes could benefit from this (once studying curios is actually worthwhile again).
