Crazy thought. Do any of the Extrasolar colonies have complex extraterrestrial lifefoms (not counting the Factors of course, who I get the impression would not be cool with what I'm about to suggest)? If so has there been any effort to clone and retrofit the bodies for morph purposes (or for that matter, Uplift). It would take a LOT of research of course (and assumes the alien biochemistry is at least neutral to our own) but one can imagine the shock value of prancing around in your tripedal bioluminiscent multijawed morph... make that character with the exposed spine in that picture SO jealous!
