Having the ability to use a full strength weapon as a fire casting tool would be a little bit too strong. Honestly the only reason the conduiz isn't broken is because the element is a bit more awkward to build for. And honestly if this was implemented right now, we would barely need tomes anymore. Weapons have the superior hit buffs so they are quite favorable, but spelledge weapons are held back by subpar scaling. There is of course mutated weapons, especially excel hasta, which are just super strong, but this imo a bit too much casting tool flexibility

So I guess we should just remove these materials then...

If anything why don't you offer a constructive alternative. If you feel "it would be too strong" then how about spells cast from these materials suffer from half weapon power like tomes do with off elements, or cast with reduced amount of swa, say a reduction of 10 to 25% from the spells swa scaling.

Also one glaring thing you've missed is that Weapons that can cast still proc parry skills, which can chunk off a good portion of the damage.
