hmm... Stone to Flesh might work as well...
SRD said:The spell also can convert a mass of stone into a fleshy substance. Such flesh is inert and lacking a vital life force unless a life force or magical energy is available. (For example, this spell would turn a stone golem into a flesh golem, but an ordinary statue would become a corpse.) You can affect an object that fits within a cylinder from 1 foot to 3 feet in diameter and up to 10 feet long or a cylinder of up to those dimensions in a larger mass of stone.
If no one has the necessary ranks in Craft to create statues (how accurate do the statues have to be, anyways? Must they be classical/realist sculptures, or would an abstract expressionist piece suffice? Would the different types of sculpts result in differently flavored brains?), *reads the post again* Dang, just realized that dead brains are off the menu. Perhaps the DM will allow you to research an alternate Stone to Brains spell?
