Oh, Lord in Heaven, yes! I spent countless hours playing with those figures as a kid, re-creating TMP (I didn't have a USS Enterprise
back then, so I flipped the original Star Wars Landspeeder upside down and pretended that was it).
Because I didn't have any of the aforementioned aliens, I used some from Star Wars. I think I had Greedo as a Romulan and Bossk as a Klingon.
