I was sort of hoping this would be how crafting works.
Some madman could potentially create a whole range of models that use the various parts you described from vanilla weapons in every conceivable permutation and then create a menu that asks which sword you'd like to craft with which hilt etc etc that will give you the appropriate model.
This solution is not particularly elegant, of course.
it should have been the way crafting works ,i don't like the way the crafting is now one bit
i guess it wouldn't have to be soooo dramatic of course.but it's all about that isn't it, fighting with weapons
