i have no expierience in modding but perhaps another approach would be :
make the wraith / hell swords unique artefacts .
so only one of each can be forged and there will be a race after them . same for the armor .

soul vortex should be removed from the spell list in that special mod then too .

and perhaps the 3-5 most used pretenders like the vq .

i don't know if everything of this is possible in a mod already but most is i think and for an expierienced modder it should take not too much time too .
