You can't just add [SOIL] to everything - it causes glitches on the surface. Massive, shiny glitches. You can, however, set all available stones to evaporate, and make them have no material value to cut down on trader losses.
I ran a fort based on this myself. I wanted to call it CracksChafe, the desert of glass, but CracksChafe isn't a valid name for a fort. Technically I have RAWs available for a Masterwork no-stone all-glass fort, along with a few extra glasses modded in. If you'd like to use those RAWs I can provide 'em.
Elaboration:
The result (of my version) is the same as normal for where tower-caps and the like will grow. I left in ores (otherwise invaders would have no equipment) but voluntarily refused to use them for anything but decoration and alchemy (and to build my first glass forges). Green, clear and crystal glass traps, weapons and armor are part of Masterwork mod, and range from copper-ish to slightly worse than steel. I elaborated on that with workable Sapphire and Diamond glass variants. Sapphire glass can be made out of crystal glass plus any variant of sapphire, including star sapphires and rubies. Diamond glass is made the same way except, y'know, made out of diamonds. Note that Masterwork includes alchemy reactions that can transmute metals into each other and can create artificial sapphires and diamonds.
I also modded in glass fibers and reactions for glass fiber clothes.
It might not surprise you to learn that I was playing the fort as a heretical babysnatching "Glass Cult" of dwarves. All other civs were hostile, no migrants of any sort, and no caravans. That could easily be undone.
