Would it be considered bad if my oracle in the campaign (Just made lvl 15, has a feat to choose) took Craft Staff & made his Guisarme into a staff? It's enchanted already. (+2 Holy Spell Storing if it matters). He's got the Haunted curse so the less switching gear around the better. I see that several staffs are weapons but are clubs or quarterstaves. It doesn't seem like too much of a stretch to make a polearm a staff to me.
