 Is there research using metallic polymers for motors or some such
conventional propulsion? I can imagine a weight savings and there must be some other
material property benefits to exploit.

Take a look at the latest Scientific American Magazine.

There's a cover article about SRI's work in developing polymer-based
actuators to replace muscle function and for similar applications. High forces and
pretty good time constants - and while there are some conductive requirements
for electrodes and such (therein lie the tricks), the stuff uses el cheapo
off-the-shelf plastics.

No RP required. You might also consider that it would be an interesting way
to build active sculptural objects - just to pique your interest.
