Crafting Question/ Item Creation

So, this is kind of a silly question but bear with me.

My character’s a power-hungry wizard. I’ve figured that he could use the Circlet of Spell-Eating cursed item to get stronger. Forcing people to wear it and imprisoning them etc. There are two problems with that, however. We don’t have much in the way of down-time in our campaign and I don’t really want to take a feat (Craft Wondrous Item) for something that may never be realized.

Is there a way for my character to be considered the “creator” of an item without, well, creating it?
