Don't forget rotation is optimal for removal.  As such superglue can be your   
   friend with a taper with  preapplied superglue to mount the i.d. of the   
   stopper-joint- which might be accessible either sacrificial or otherwise   
   (scoring with a dremel diamond    
   disk if possible).  Taper insert can be anything around.  The taper is your   
   rotational handle obviously.  Heating and cooling are risky but in the most   
   simple of situations.
