Blade Runner - uncredited dolls?

[Corey Fantoccini]

I've been to see the new "Final Cut" of BLADE RUNNER recently - still as awesome as I remember it from years back. And naturally, as an LM fan, I do fancy the moments in J.F. Sebastian's lair, since among his toys he has two pretty automata.

The two actresses who play his dolls are not credited on screen, nor can I find any data at the imdb. They were probably just dayplayers who were hired for their mime and posing skills, but have they ever been identified in some other story on the movie? It seems like everyone else who had screen time in the movie has been identified somewhere.
