Hello, I am leading development on the soartex Fanver texture pack and want to clear a few things up for you guys. Consider this permission to redistribute all of the textures in Fanver, but only for Minetest. You may not add an adf.ly link to it, that wouldn't be fair to the community.
I am not very familiar with minetest, but Stef, using the decorative menu backgrounds to recreate soartex is hilarious. That has to be the hardest way to convert this pack. Download soartex from here:

The green grass in the customizer was made by soar, the original author of soartex. There is also a version of the jungle leaves in their original green color. I can recolor the rest of the leaves myself if you need help with that.
If there are any textures in Minetest that are not in Minecraft vanilla, let me know. Soartex has a massive gallery of textures for mods, and I'm sure those could fill in any gaps.
Edit: Minetest has different rails, so I pulled this texture sheet out of soartex Railcraft mod support:
Here is also a cross rail texture:
EDIT @Jordach: I am not interested in taking on this project myself. I am more than busy with Minecraft soartex development. I would be thrilled if you kept up your work on this! The point of this post was to give permission and give a few pointers.
