I had thought about adding support for Blood Magic and even looked into the code to do it... I'll have to see if it's still feasible to do.
I'll have to take a look into Bewitchment and Nature's Aura as I haven't played with them yet. I didn't even know Roots 3 was a thing either.
As far as Astral Sorcery goes, I would have to see how feasible it would be to add the Crystal growth and dulling mechanics to my weapons before I can say for certain.
I'm not sure if I would be able to add Psimetal weapons from Psi, but I'll take a look into it...
Abyssalcraft should be straightforward to add provided there are no special behaviours for weapons in that mod.
I'm not entirely sure what materials exist in Vampirism, apart from Silver, that exist in that mod. I'll have to look into that as well.
I've not played with EvilCraft for a very long time, so I've forgotten what that mod even contains.
The following magic mods add their own materials for weaponry:
Bewitchment Nature's Aura Roots 3 Astral Sorcery Blood Magic PSI Abyssalcraft Vampirism Evilcraft
There are some others I can think of, but they are handled by other addons already
