I suggest that one could modify the q7 weapons with q1-q6 weapons, with one or several of them. Either one place for each of the q1-q6 qualities adding some influence or they could add an extra hit or two. There are many options how they could be used. This way people would use them more, they would need to use them.
Of course it could be so that you need an extra building which makes it possible to do the modification. Anyway, just an idea.
