If you want you can, they're all just ripped and converted packages from misc ZH scriptsets. I wouldn't recommend converting them into the distro though, might be a lot of work. I'd suggest just taking the books, spell names, manacosts, delays, effects, etc and incorporate them into your spell system.
The enchantment book has it's own little system of casting spells, which is pretty organized, so that may be easily converted.
Fyi, I don't think I'll be able to contribute to the distro anymore. And if I do it'll be a really rare occasion.
Sorry,
