So I'm getting back into watching Farscape, a sci fi tv show I really enjoy, where half breeds between extremely different species is possible. The main antagonist is a half breed between the show's human species and basically overpowered trandoshans, and I feel like a nemesis based around this half breed character would make for an extremely engaging story.
Basically in star wars they aren't exactly clear how interspecies stuff works, and the only canon info we have is a clone that had half breed babies with a twilek from the clone wars tv show. Twileks and humans are similar enough to make a case for interspecies reproduction but I don't want to get into too much of the science and biology because its star wars and you can't think about that too much.
My question to you all is do you think I could get away with a nemesis half breed between a human and trandoshan or some other freaky race, or would I need to go the biological experiment gone wrong route. Any opinions would be appreciated.
