Looking for something that allows for the cannibalization of unwanted magic items. In my current game our party has kind of an unusual composition, and we have trouble using a lot of the standard treasure we come across. We also have very limited access to markets that would let us sell them, so I'm looking for alternate ways of dealing with the issue. I have several item creation feats so far, and the GM is amenable to other options.
One sneaky trick you can do within the rules is add the "transformative" quality to magic weapons you already found, and then have them transform into other weapons you can actually use.
It's kinda cheesy, but it's there in the rules.
