bersism ... you should not have a problem. You will need to seal the clay and use proper release procedures, but the same technique should be fine.

I would like to make a mold of a plasticine letter sculp i did, as plasitcine wont dry out and cant be fired do you think this technique would be suitable?, click my page to see sculp. Any information would be greatly appreciated.
