Not a potter so I may be misunderstanding - but if you mean making a stamp out of something else (acrylic for example) in order to push patterns into clay, then not as far as I know, but it would 100% work. Acrylic or wood (or Delrin which is extra sturdy stuff) make great stamps for leather. The process would be likely almost identical for clay 
Rolling pins are also definitely an option. I started a project to attach a veneer with engravings to a rolling pin (since I’ve never set up a rotary station to engrave directly into a round object) but it never got further than the design phase. If you do something like that I’d be thrilled to read about it
