Using Github's search function, I have not found anything a suggestion like this.

Suggestion
Pyrotech already has crystals and crystal chunks for redstone and quartz, but not for glowstone. Shame, because glowstone crystals would look rather good with the same block model used for redstone and quartz crystals. (And I dislike how vanilla's glowstone crystal structures look). They can be mined to give glowstone chunks, which are subsequently crushed on an anvil to give glowstone dust.
One thing I leave up to you would be whether these glowstone crystals are hanging from the ceiling like stalactites, or stand on the floor like stalagmites.
