Alchemy - Transmutation of Logs & Rocks for aesthetics

[Vydrion]

Not sure if this idea was mentioned before, so my apologies if this is a repost.

I'd like to see alchemy cover the topic of 'mundane' transmutation: Changing a rock or log into another.
The idea is purely to be able to obtain the rock or log you want for aesthetic purposes, so metals and special rocks (cat gold,...) aren't part of my initial idea (although that would be a cool topic to discuss)

The recipe should be obtainable relatively easily (alchemy table & tools that dont need precious metals) and not cost too much.

Overlaps too much with sketchbook functionality imo.

Why not alchemy unique materials instead?
