A while ago I retextured some of the blocks and items in the fairly popular mod Draconic Evolution, inspired by CyanideX's Unity resource pack. I finally finished most of the textures and uploaded my resource pack to Curse! It retextures all of the tools and armors (YOU MUST ENABLE OLD 2D ARMOR AND TOOLS IN DE'S CONFIG) along with many items.
Here's some preview screenshots (same as on the Curseforge page):
The Meaning of Life, the Universe, and Everything.
Wow, surprised I did not find this before! Have you been able to do any more of the textures? Would like to possibly consider using this as the default texture source for DE if you can convert every texture in the mod
