Now that we have a method of decaying paved tiles (Hell yes finally!), I would love to see an option to rip up the vines off of tiles that are decaying with a (very) small chance of pulling up a curiosity called a "Tangled Relic" with flavor text of "Wrapped in vines and sodden earth, a hidden relic of the hearth."
Doesn't need to be a great curio, and it's probably too much to ask for that it be something that was dropped on the ground to decay in the area in some age past converted to a curio.
